A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite. ... FM Radio Transmitter Circuit Diagram. If ...

This carrier frequency can be varied using the 20pF variable capacitor connected with the inductor, and the typical frequency band of this particular design is between the 88MHz to 108MHz and since ...

The circuit is built around dual D-type positive-edge-triggered flip-flop 74AC74 (IC1), ripple-carry binary counter CD4060 (IC3 and IC5), low-power audio amplifier LM386 (IC6), phase-locked loop ...

This four stage FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around ...
