V (U00). EXT_SWB+: Q009.. Control Module Powering On/Off The mobile radio can be powered on/off through any of the following methods: Power On/Off Key Ignition Signal Emergency Alarm Power On/Off Key To turn on the radio, press the Power On/Off Key, and R08 becomes grounded and Q0 is turned on. Then Q008 of PNP transistor outputs a high-level signal, causing U006 to start working. Afterwards, the processor U00 will run the user programs to keep the power control signal Pwr_Hold at a high level. In this case, the radio starts to work properly after the Power On/Off Key is released. To turn off the radio, press the Power On/Off Key, and Q0 is turned on and a low-level signal Pwr_On_Det to power off the radio is detected by U00, which then controls Pwr_Hold to output a low-level signal. Afterwards, the radio is powered off. Ignition Signal When the voltage of ignition signal exceeds 7 V, Q0 will be turned on by C06, R09 and R0. As a result, the PNP transistor of Q008 will be further turned on to supply power for the whole system. Meanwhile, Q0 will also be turned on, and U00 will identify ignition signals by detecting the signal from Q0; afterwards, the level Pwr_Hold is generated by the processor.

23 Circuit Description UHF (00 70 MHz) Emergency Alarm When the emergency alarm pin is at low level, R08 is grounded, and Q00 is turned on to supply power for the whole system. Meanwhile, Q0 is also turned on. When low level is detected from U00 but the radio is powered off, the system will output the level Pwr_Hold and send emergency alarm signal. If the radio is powered on then, the system will directly output emergency alarm signal. Power-up Process Step Power on the radio using one of the three methods (Power On/Off key, Ignition Signal, or Emergency Alarm). Step U0 generates reset signal and remain a low level for. seconds, allowing the processor to get started. Step Power-on signal will be sent to the processor. Step After receiving the signal, the processor generates the level of Pwr_Hold. Then the power-up processes are completed. Clock Input Clock The K clock provided by X00 is mainly used for timing and sleeping of the system. The frequency of the K clock is.768 khz, which is divided by U00 by 768 times in all to Hz for counting seconds. The system clock (9. MHz) is generated by an external crystal oscillator. Output Clock The baseband outputs clock signals to send to U00, U800 and Option Board respectively. 6

24 UHF (00 70 MHz) Circuit Description.. Interface Distribution SPI Interface SPI interface of processor U00 operates in Master Mode, and is controlled by MPU or DMA. In Master Mode, U00 can provide chip select signals, of which CS is used to control the IF processor U600. MCSI Interface When communicating with U800, U00 works in Master Mode with clock frequency of up to 9.6 MHz. U800 uses MCSI synchronization as chip select signal and MCSI.DOUT as data cable to configure its register. MICROWIRE Interface The MICROWIRE interface can accommodate external devices at most, which is generally used for transmitting control and status messages of external devices, and reading data from ROM. Its maximum clock frequency is a quarter of system clock frequency. In this case, MICROWIRE is used to configure or read from the audio processor and requires chip select signal CS. 7

25 Circuit Description UHF (00 70 MHz) SSI Interface U00 has a total of three McBSP interfaces: McBSP, McBSP and McBSP, and it is compatible with various interfaces. McBSP is connected to the IS interface of the audio processor, to realize two-way transmission of digital voice and data. McBSP uses independent clock and frame synchronization for transmission and reception. The SSI of the RX processor is connected to the RX end of McBSP. U800 is connected to the TX end of McBSP. U00 works in Master Mode. McBSP is connected to the Option Board interface for both voice and data transmission. USB Interface The radio has two external USB interfaces, which are connected to the same USB signal port of the processor. REF CLOCK is the reference frequency in specified mode. It should be MHz in high rate mode or. MHz in low rate mode. 8

26 UHF (00 70 MHz) Circuit Description UART Interface Processor U00 has a total of three UART interfaces, which are used to communicate with different external devices. UART is used for communication with Option Board and accessory connector. Mobile Accessory Connector (MAC) Mobile accessory connector contains audio interface, programmable I/O port, serial port, USB port, accessory identifier port, etc, which are available for further development. Please refer to 7. DB6 Accessory Interface for details. Option Board Interface J00, an option board interface, is used to achieve specific function by connecting to the designated option board.

This bus is composed of CLKX, FSX, DX and DR. The bus sends the 6-bit demodulated PCM audio signal to the Codec, and adjusts the signal to appropriate amplitude according to the volume (RMS should be 80 mv when frequency is khz and deviation is khz). Then the Codec converts PCM data into analog audio data via DAC. U00 provides two outputs: SPK and SPK. SPK is amplified by U00 and then is fed to the PA U00, to derive two outputs of received audio, which will be applied to the front panel speaker and further development interface respectively. SPK is amplified and divided into the four paths of signal

29 Circuit Description UHF (00 70 MHz) HANDSET_AUDIO, RX_AUDIO, PUB_ADDESS and PUB_ADDESS. The first two paths are amplified by U00, and the last two paths are amplified by U006. Output of HANDSET_AUDIO, PUB_ADDESS and PUB_ADDESS are controlled by Q00, Q006 and Q00 respectively. TX Audio Path The audio processor U00 has two MIC inputs: the internal MIC and external MIC. The internal MIC is connected to the MICIN_HND of U00, and is combined with AUX to provide differential input. After 9. V is divided by R07 and R09, a bias voltage of about 7 V is provided to the front panel MIC. The external MIC is connected to the MIC_HED of the Codec as a uni-directional input. Both MICs are switched by Q00. When the internal MIC is active, EXT_MIC_EN is at low level, bias voltage of external MIC is disconnected, and the ADC in U00 samples voltage at the MICIN_HND. When the external MIC is active, EXT_MIC_EN is at high level, Q00 is turned on, bias voltage is connected, and the ADC in U00 samples only audio data at MICIN_HED. Audio signals input from the MMC interface or the accessory connector, are fed to the Codec (gain of Codec is programmable via the CPS) and then are converted by the ADC into 6-bit PCM digital audio, which will be fed to U00 via the SSI interface. When the radio is set to operate in loudspeaker mode, audio signal is generated by the internal MIC, and then is buffered by U00, and finally is output via SPK. The output audio signal is amplified, and then is output as the two paths of audio PUB_ADDRESS and PUB_ADDRESS.. RF Section.. Transmitter Circuit Transmitter Circuit The transmitter circuit is composed of power amplifier circuit and power control circuit. The power amplifier circuit is used to amplify the VCO signal to the appropriate output power level, while the power control circuit can keep the output power at the appropriate level, so as to protect the power amplifier from damage caused by over heat, antenna mismatch, and out-of-range voltage (over voltage or under voltage may result in damage to Q70, Q70, Q700 and Q70).

The first stage is a buffer amplifier circuit with fixed gain; the second stage is a pre-driver power amplifier circuit with variable gain (formed by Q70); the third stage is a driver power amplifier circuit with variable gain (formed by Q700); and the final stage is the final power amplifier circuit with fixed gain (formed by Q70). In addition, TX power amplifier circuit contains a TX/RX switch and a low-pass filter. TX Buffer Amplifier The first stage (Q70) provides about 6 db power gain, and adjusts its bias circuit to get a quiescent bias current of 8 ma (for Q70). Power supply for the switching transistor Q7007 is controlled by TX signal (enabled by antenna switch), so as to further control the power supply for Q70. Pre-driver Power Amplifier The pre-driver power amplifier is formed by Q70, with variable gain controlled by voltage VGG. The input matching circuit is composed of C70, L70, L707, C70 and R707. Driver Power Amplifier The driver power amplifier is formed by Q700, with variable gain controlled by voltage VGG. The maximum output power is +8. dbm, and the maximum adjustable gain is db. Final Power Amplifier The final power amplifier consists of Q70, with the maximum output power of +. dbm, and the maximum adjustable gain of db. The PA input matching circuit is composed of C7, C7, R707, R70, R70, R70, R706 and R708, while the power combination matching circuit is composed of C70, C700, C7099, C708, C70, C7086 and C7087. Antenna Switch The antenna switch is used to switch between the transmitter circuit and the receiver circuit. In TX mode, TX signal controls the switching transistor Q7007, to further control the power supply 8 V A for the PIN

31 Circuit Description UHF (00 70 MHz) diodes D7007 and D7008. Quiescent bias current of the PIN diode is controlled by the resistors R7 and R707. In this mode, D7007 is turned on; RF signals are sent to the low-pass filter (composed of C7, C7, C79, C7, C7, L70, L70 and L70) and then transmitted via the antenna port. In RX mode, TX signal controls the switching transistor Q7007, to further disconnect the PIN diodes D7007 and D7008, so as to supply power. When the two PIN diodes are disconnected, signals feed into the RX path through the low-pass filter (composed of L706, C777 and C778). Low-pass Filter The low-pass filter is composed of microstrip inductors and capacitors (C79, C7, C76, C7, C7, C7, C77 and C70) and is used to suppress harmonic energy from the PA. Directional Coupler The directional coupler is composed of microstrip directional coupler, L70, R700, R70, R7098, L708, R7097, R7099, R7096, etc. And it is used to detect both forward and reverse power of the operating transmitter. The forward power is coupled to the diode D7006, and the voltage is input to the power control circuit (U700). Then the voltage VGG is output to control the gate voltage of pre-driver and driver PA, ensuring a constant power output. The directional coupler can adjust the TX power and detect the VSWR load. The reverse power is coupled to D700. The output voltage is then sent to U700 for detection. Output Power Control The TX power is controlled by power control chips U700 and U700 of the transmitter. The forward power is coupled to the directional coupler, to output a voltage that can represent the forward power. The voltage together with the preset output voltage are sent to U700 and U700 to output a voltage VGG, which can control both gate voltages and gains of Q70 and Q700, ensuring a constant power output. Temperature Protection The voltage division circuit consists of thermistor RT, resistor R709 and R7060. The output voltage is proportional to the detected temperature. Both the voltage used for temperature detection and the threshold voltage are fed into the operational amplifier U00 to output a voltage signal that is in proportion to the detected temperature. Afterwards, the voltage is sent to software for detection, and then the preset voltage will be subsequently changed to reduce the TX power, and to protect the PA from over-heating. Pressure Pad Switch The power control circuit includes a pressure pad switch SW, which is controlled by the conductive rubber part mounted on the upper cover. When the switch is turned off, VGG will become low, and no power will be output from PA. Otherwise, PA will work normally.

32 UHF (00 70 MHz) Circuit Description.. Receiver Circuit The receiver utilizes double conversion superheterodyne technique. The first IF is 8.0 MHz and the second IF is. MHz. The first local oscillator signal is provided by the PLL circuit U800, and the second local oscillator signal (.8 MHz) is provided by the PLL circuit U600. The major units are BPF and LNA, Mixer, IF filter, IF amplifier and IF processor. LPF LO 8VA Attenuator ANT OSC level:> 7dBm Attenuator Control 0dBm Band-pass Filter LNA Band-pass Filter OMAP VA&VD&VA AD986 VA.0 MHz 8VA IF Processor IF Amp IF Filter Mixer TV Receiver Front-end RF signals are sent to the low-pass filter to remove out-of-band signals, and are applied to the two-stage electrically tunable band-pass filter to acquire useful signals. After passing through the RF band-pass filter and LNA (Q60), the RF signals together with the first LO signal are sent to the mixer for the first frequency conversion, to generate the first IF signal of 8.0 MHz. The mixer that employs the passive diode can ensure good dynamic range and port isolation. The LO signal ( dbm) from the VCO is sent to Q60 to acquire a gain of 7 db. The first LO signal (8.0 MHz) passes through the crystal filter (Z600) to filter the out-of-band spurious signals, and then is sent to the two-stage IF amplifier circuit (composed of Q6006 and Q6007) for amplification. Finally the amplified signals go to the IF IC for digital processing.

33 Circuit Description UHF (00 70 MHz) Receiver Back-end The first IF signal (8.0 MHz) output by the IF amplifier goes into IF IC via Pin 7, where the signal is converted to the second IF signal (. MHz). Then the un-demodulated digital I/Q signal output from the SSI interface is sent to U00 for demodulation. IF IC employs a reference frequency of 9. MHz and it shares the crystal with U00 and U800. The second LO VCO consists of the external transistor, varactor and relevant components, to provide the second LO signal. The 8 MHz clock frequency is generated by the LC (D600, L60, C607 and C60) resonance loop circuit. DSP (U00) acquires the audio signal from IF IC (U600). Then this signal goes through U00 to output data signal, which is sent to U00 and Pin (SSI_DI) for digital-to-analog conversion... Frequency Generation Unit (FGU) PLL Synthesizer The PLL synthesizer that consists of the reference oscillator (X800), PLL IC (U800) and VCO, is utilized to supply excitation signal source to the transmitter, and local oscillator signal to the receiver. erence Crystal Oscillator erence crystal oscillator (X800) employs a 9. MHz TCXO, and its reference frequency is calibrated by the digital-to-analog converter IC (U800) for accuracy. PLL IC The PLL IC (U800) employs a fractional frequency divider IC. The logic switch ICs (U800 and U800) work with the PLL IC (U800) to achieve locking. 6

34 UHF (00 70 MHz) Circuit Description The 9. MHz frequency generated by reference crystal oscillator (X800) goes into PLL IC (U800) for division, generating the reference frequency. Meanwhile, the frequency generated by VCO goes into PLL IC (U800) for frequency division. The resulting frequency will be compared with reference frequency in terms of phase difference in the phase detector. After comparison, the resulting frequency is converted to CV voltage via the loop filter, to control and lock the frequency. VCO The VCO is composed of transistors (Q800 and Q007), varactors and four Colpitts oscillators. There are two VCOs in all. One VCO (Q800) is used to transmit excitation signals and the other VCO (Q8007) is used to receive LO signals. U00 controls the operating frequency of the VCO. Q800, Q800 and Q8006 constitute the buffer amplifiers for both the transmitter circuit and receiver circuit. The digital-to-analog converter IC (U800) modulates the TX oscillator signal. 7

GPS Circuit GPS Antenna Power GPS module UART OMAP REB-LPX Palm Microphone LCD GPS positioning information can be acquired via the programmed GPS key on the front panel. The GPS function is realized via REB-LPx module, which internally integrates GPS baseband processor circuits. The GPS signal (.7 GHz), received via the GPS active antenna (with a built-in LNA), goes to the GPS module for processing, and then enters U00 via the UART port. Meanwhile, U00 sends control command to the GPS module and forwards processed GPS information to the palm microphone LCD via USB. 8
