The.0 MHz signal is passed through two HPFs (L0, C0, C0 and C0), splitter (L0, L0, C0 and C), db attenuator (R to R) and (L, C to C), and then applied to the frequency multiplying circuit (Q), which extracts the rd harmonic component, resulting in the.09 MHz reference clock signal. The clock signal is amplifi ed by the clock AMP (Q), and passed through the db attenuator (R to R) and SAW fi lter (FI), and then applied to the DDS (IC0). Using the.09 MHz reference clock signal, the DDS (IC0) directly generates the. to. MHz st TX/ RX L signal. The st TX/RX L signal is passed through the (L, L, C to C) and db attenuator (R to R), and then applied to the L AMP (IC0). When the operating frequency is 00 to 0 MHz, the st TX/ RX L signal is passed through the (L to L, C to C), instead of the db attenuator (R to R). The amplifi ed signal is passed through the (L0, L0, C, C and C), and applied to the frequency multiplying circuit (D0 and L), which extracts the nd harmonic component, resulting in the. to. MHz signal. The st TX/RX L signal is then passed through either. When the operating frequency is 0 to 0.999 MHz, the st TX/RX L signal is fi ltered by the (L to L, C to C). When the operating frequency is 0.0 to 9.999 MHz and 0 to 0 MHz, the st TX/RX L signal is fi ltered by the (L0 to L0, C0 to C). The fi ltered signal is passed through the db attenuator (R to R), and then applied to the L AMP (IC). FREQUENCY CNFIGURATIN DIAGRAM.0 MHz X00(TCX) Q0 Q IC0 Reference frequency. MHz X X st L DDS 0.
