10 watt RF amplifier for 18MHz by 2SC1969

Advertisements

This project and your efforts will provide you with a 0.55…3 watt input to easily 10 watt output. The two linear amplifiers are ment for use with QRP SSB/CW/FM/AM transmitters on the amateur bands 15 and 17 meters can be powered from a 12 volt DC supply. The design is a good balance between output power, physical size. The completed amplifier will reward the builder with a clean, more powerful output signal for a QRP rig when radio conditions become marginal.

#T1 2SC1969 (only Mitsubishi type!!), ERF-2030, 2SC1173, 2SC1944
(with proper heatsink isolated from the transistor)
#T2 BC338, 2N2222
