1W-cwtransmitter


Posted on Jun 18, 2012

This is a little transmitter that could be put into a plastic Easter egg. It delivers approximately 1 W of measured rf output into a 50-0 dummy load, and creates no heating problems with the circuit. The crystal is a series fundamental type, and the power source provides 9 V with a 2-A supply. The transmitter can operate at another frequency, but C1 and C2 might have to be changed for the circuit to work properly.
