3W FM Transmitter


Posted on Feb 4, 2014

This is the schematic for an FM transmitter with 3 to 3. 5 W output power that can be used between 90 and 110 MHz. Although the stability isn`t so bad, a PLL can be used on this circuit. This is a circuit that I`ve build a few years ago for a friend, who used it in combination with the BLY88 amplifier to obtain 20 W output power. From the notes tha

t I made at the original schematic, it worked fine with a SWR of 1 : 1. 05 (quite normal at my place with my antenna). 2. The circuit has been tested on a normal RF-testing breadboard (with one side copper). Make some connections between the two sides. Build the transmitter in a RF-proof casing, use good connectors and cable, make a shielding between the different stages, and be aware of all the other RF rules of building.
