TK-7102H CIRCUIT DESCRIPTION ■ IF Amplifier Frequency Configuration The first IF signal is amplified by Q351, and the enters The receiver utilizes double conversion. The first IF is IC301 (FM processing IC). The signal is heterodyned again 49.95MHz and the second IF is 450kHz. The first local oscil- with a second local oscillator signal within IC301 to create a lator signal is supplied from the PLL circuit.
