FM transmitter circuit without coil

This is FM transmitter circuit without Coil, using inverter digital IC as main and controlled frequency is precise by a crystal. In Figure 1 is RF oscillator circuit which use an inverter IC1/2 and ceramic crystal filter 10.7 MHz to use drive IC1/4 – IC1/6 by through IC1/3. Figure 1 the circuit diagram When inverter … Read more
