A 36 W, V-band, solid state source

A 36 W, V-band, solid state source with <1 deg/dB of AM/PM distortion has been demonstrated. The source joins low loss RF spatial combining techniques with high thermal capacity, high density, multi-layer substrates, enabling a breakthrough for the generation of millimeter-wave, solid state power. Subsequently, using 0.1 /spl mu/m PHEMT MMICs allows low AM/PM distortion. To the author's knowledge, this paper's result is the highest V-band solid state power recorded.
