A very simple FM CB radio receiver circuit can be designed using this electronic diagram below.
This FM CB radio receiver circuit is designed using an TCA440 integrated circuit. The receiver works with a intermediate frequency of 455kHz.
Input filter is 27MF ceramic type. Since the intermediate frequency filter transformer is used without adjustment, remote selection is 40dB.
This compact design FM stereo decoder circuit is designed using the TDA7388 IC manufactured by ST Microelectronics .
The TDA7338 is a monolithic integrated FM stereo decoder circuit with noise blanking for FM car radio applications.
With the used BICMOS technique, the 19KHz Notch Filter, the PLL Filter and Phase Filter is realized on the chip with a Switched Capacitor concept.
