350W LINEAR VHF 6 and 4 50-75 MHz NEW
A brand new built Unit. A solid state High power HF linear amplifier built on newly designed circuit board. On a good ground plane. 2 mosfet's in push pull circuit. Amplifier is built with the best components and the bias circuit had been developed to employ modern devices (3 leg) and a current source with an exact control of output bias to the gates of the final transistors. Temperature tracking of bias is employed where the sense device (Diode) is attached very near the bases of the power transistors.
The circuit is very stable at all power levels. 5-7 W in puts 250-350 W out on a 50 ohm dummy load at 48v V. The current is about 16-20A. Idling current can be adjusted with a variable resistor on board to meet class AB of operation.
