800 Watt Mosfet amplifier with 50V high power RF mosfet for 144Mhz Amateur Radio

This is a 800W 144Mhz mosfet Amateur Radio amplifier. Noteworthy compression sets in above 800 Watts. The maximum output is 1.1KW and efficiency is around 63% at 23dB gain with only ONE high power 50V rf mosfet. In the meantime I’ve combined two of these devices (homebrew 3dB 90 degree hybrids). The amp draws 50.5 Amps at 50 Volts and puts out 1450 Watts with 10 Watts of drive power. In CW this amplifier is capable of producing around 2KW but linearity suffers above 1.5KW and SSB use is not recommended at this power level. These devices develop a large amount of heat which has to be removed by forced air cooling or liquid cooling.

VK3VCM portable HF Amateur Radio – Christmas Eve 2010

Operating portable HF from Gellibrand Park, in the suburb of Williamstown, Melbourne Australia on Christmas eve 2010. A quick look around the location and portable set up which consisted of a Buddipole Deluxe configured as a 40m dipole mounted on a tripod & 22 foot extendable mast. My transceiver is the newly released Kenwood TS-590s running 100 watts. Among the contacts made, I ended up having a very enjoyable QSO with Peter VK3YE who was also operating portable while visiting Southern Tasmania running QRP 5 watts on a Yaesu FT-817. A most enjoyable afternoon on HF from a beautiful location.
