OSC CIRCUITS From [REF I/O] (CONNECT-B; J) Q/Q MHz EXT-REF IN BUFF Q.. MHz Standard signal PLL UNIT PLL UNIT supplies the LO (Local Oscillator) signals (st, nd, rd and th), still more the clock signals for DSP circuits. To obtain physical strength for the VCO, VCO, DOUBLER, FIL and FIL BOARDs, these circuits are shielded and isolated perfectly, by being patterned separately on different P.C. boards. VCO BOARD VCO BOARD has tree VCOs ;VCO-A, VCO-B and VCO-C. VCO-A (Q), as an example, is a colpitts-typed oscillator circuit, and its output signal is buffered by Q and output via diode switch. Q controls the power supply for the VCO, and the voltage of LHV line adjusts the oscillation level for suitable LO signal level. The buffer-amplifi ed VCO output signals are divided by the divider, and applied to the LO amplifier via attenuator (as a pad). The amplified LO signals are applied to the RF-A UNIT or FIL BOARD as the st LO signals, via fi lters and amplifi ers. EXT-REF OUT LPF MHz Q LPF MHz SC Q BUFF Q X (.MHz OCXO) The VCO-A is mounted on the nearest to VCO board to reduce the signal loss. The resonators are employed strip lines which had been used with SMD electric parts. The oscillating frequency ranges are divide into three for wide oscillation frequency coverage.

12 VCO BOARD VCO BOARD provides the nd LO signals for receiving the both of VHF and UHF bands, and contains VCOs oscillating MHz, MHz and. MHz LO signals. The MHz band VCO is a totem pole typed one with bipolar TRs (Q and Q). MHz, and.mhz band VCOs are employed tank typed resonator with FETs (Q and Q) to obtain good C/N capability. DOUBLER BOARD st LO signals for receiving GHz and below frequency are doubled by doublers on the BOUBLER BOARD. IC-R employed doubler which produces st LO signals for the receiving. GHz and above, and improved the IP characteristic and sensitivity, and more, destroyed the necessary of the converter circuits. The doubler circuit is balanced type and composed by bipolar transistors (Q, Q). The employment of transistors improved lower conversion loss than by diodes, and the same capability of attenuating odd numbered harmonics as by diodes. FIL BOARD Fil board doubles and fi lters the st LO signals for recieving VHF and UHF bands. To suppress the directly oscillated frequency (Fosc ) MHz and harmonics (Fosc N) MHz, three staged fi lters are used. FIL BOARD Fil board doubles and fi lters nd LO signals. By expanding the pass band width of the, the commonly used for the st LO signals genarated by MHz, MHz and.mhz VCOs. MMIC (IC) is inserted in front of the fi lter to make up the st LO signal level.
