Page 79: Circuit Description
RMV800 SERVICE MANUAL Circuit Description 1. Frequency Configuration The receiver utilizes double conversion superheterodyne. The first IF is 49.95MHz and the second is 450KHz. The first local oscillator signal is supplied by PLL circuit. The second local oscillator signal (50.4MHz) is generated from the frequency tripling of TCXO (16.8MHz).
Page 80 RMV800 SERVICE MANUAL IF Amplifier The first IF signal is amplified by Q125, Q118 and then enters IC119 (TA31136FN). The signal is mixed with the second local oscillator signal (50.4MHz) to create a 450KHz second IF signal. The second IF signal is then fed to a ceramic filter (N: CF101, CF103;...
Page 81: Pll Circuit
RMV800 SERVICE MANUAL 3.2 Driver and Final Power Amplifier Circuit TX-RF signal is outputted from Q703 in VCO circuit and amplified by Q126, Q127 and Q128. The amplified signal is then fed to IC102 (Power Module) and passes through LPF before reaching the antenna terminal.
Page 82 RMV800 SERVICE MANUAL 5. Control Circuit Circuit in this section is comprised of CPU, reset IC, power supply controller and flash ROM. 5.1 CPU IC120 (CPU) operates at 9.8304MHz. It controls the data transmission between receive circuit, transmit circuit, control circuit, display circuit and peripheral circuit.
Page 83 RMV800 SERVICE MANUAL 6. Display Circuit Display circuit is comprised of CPU (IC503), LCD module, LED and other components. Radio features are programmable by PF1-PF6. Data is displayed on the 12-digit and 4-digit dot matrix LCD in alphanumeric form. Figure 6 Display Circuit...
