Abstract : One scheme under consideration for aircraft communication via a satellite envisages the use of a multi-element aerial array at L-band (1.54 GHz to 1.66 GHz) each element simultaneously transmitting 10 W. This paper describes an experimental system capable of feeding two aerials at 1.6 GHz. This is achieved by frequency multiplication and power amplification of an existing 400 MHz power source. Two frequency doubling stages are used in each arm of the system. A UHF power transistor is used in the varactor mode to produce power gain in addition to frequency doubling, and this is followed by a step-recovery varactor frequency-doubler producing 10 W at 1.6 GHz.
