2M-1KW

This amplifier design is a rugged linear amplifier for the 2 meter amateur band (144 MHz - 148 MHz) operation. Because of the ruggedness and low thermal resistance of the MRFE6VP61K25H transistor used in the design, the amplifier can output high power even when operating into high VSWR.  The amplifier can be biased for Class AB linear or Class C operation and is suitable for both analog and digital waveforms (AM/SSB or WSJT/FM/CW).
