Current position: Home > Circuit Diagram > 1-W CW TRANSMITTER


 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-Ω 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. The secondary of L1 is wound over the center of a 10- μH coil, with five turns of #30 enameled wire.
