5 Watt, Solid State, EHF Transmitter.

Abstract

A 5-watt, all solid-state, EHF, rugged, broadband transmitter has been developed for use in satellite-communication ground terminals. This state-of-the-art transmitter demonstrates efficient and cost-effective RF power generation at EHF for commercial and military applications. The specific center frequency and bandwidth (43.5 to 45.5 GHz) are matched to current military requirements. Measured results on the prototype unit are presented. Measured data on the combined outputs of two solid-state, EHF transmitters show 10.5 watts at 44.5f GHz, and the 1-dB bandwidth in excess of 5% (2 GHz). Development of the building blocks (the diodes, the unit amplifiers, the power combiners and the multiplier) are also discussed. Keywords include: EHF technology; Added power; Unit amplifier; Gated operation; RF power generation; Reflection amplifier; Power combining; Frequency quadrupler; IMPATT diodes; Circulator; and EHF transmitter.
