A Ka-band planar tripler based on a stacked symmetric InP heterostructure-barrier varactor

The symmetric heterostructure barrier varactor (HBV) lends itself to frequency tripling with no need for bias or for a second harmonic idler circuit. This paper presents the performance of the first planar microstrip Ka-band frequency tripler based on a stacked HBV structure. A minimum conversion loss of 11.2 dB with a maximum power output of 10.78 dBm at 40.35 GHz is obtained.<
