Transistor radio application circuit of the ceramic filter
The transistor radio application circuit of the two-port and three-port ceramic filter. The ceramic filters B1 and B2 can be used in the 465kHz intermediate frequency bypass, the B1 can be used in the coupling of the intermediate frequency. B1 uses the narrowband type filter, and it is connected with the emitter resistance of the VT1, this design helps to eliminate the interference and noise.
