IF signal through a coupling capacitor c] ol Qioi added to the base, is amplified by the collector output, and then through a coupling capacitor C103 is applied to a surface acoustic wave filter XjoJ input device (the coupling capacitor has a DC blocking effect). Inductor Lioi and collector load resistor R106 in parallel Qioi, the use of high-frequency signal L10l high impedance characteristics in the pre-amp to compensate for high-frequency characteristics.
