FM intermediate frequency amplifier circuit composed of ceramic filters

Shown is an FM intermediate frequency amplifier circuit composed of ceramic filters . The FM intermediate frequency amplifier circuit is mainly composed of intermediate frequency input
transformer T], ceramic filter CF1, intermediate frequency amplifier VT1 and intermediate frequency transformer T2. It is usually available Used to amplify FM intermediate frequency
signals.
    The intermediate frequency (10.7 MHz) signal from the FM front-end circuit is first sent to the primary winding of the intermediate frequency transformer TJ. This winding and cs form an intermediate
frequency resonant circuit with frequency selection function. The secondary of the transformer Tl is connected with a 10.7 MHz ceramic filter. , it sends the selected intermediate frequency signal
to the base of the next stage intermediate frequency amplifier transistor VT1 for amplification. The amplified signal of VT1 is then output to the next stage through the second intermediate frequency transformer Tz
. This circuit has the characteristics of simple structure and good performance.
