A One-Kilowatt Airborne-Radio-Frequency Power Amplifier

Abstract

A miniaturized airborne rf power amplifier with continuous coverage of the 4-30-mc frequency range and with 1-kw average power output is described. Complete oil immersion for heat transfer and voltage insulation plus a novel six-phase self-rectifying power amplifier circuit give a high-power density unit capable of operating under extreme environmental conditions. The maximum usable power level is now limited by the aircraft antennas available.
