FM transmitter using UPC1651


Posted on Feb 5, 2014

Here is the circuit diagram of an FM transmitter using the IC UPC1651. UPC1651 is a wide band UHF Silicon MMIC amplifier. The IC has a broad frequency response to 1200MHz and power gain up to 19dB. The IC can be operated from 5V DC. The audio signals picked by the microphone are fed to the input pin (pin2) of the IC via capacitor C1. C1 acts as a n
