An InAlGaAs/InP based heterostructure barrier varactor (HBV) frequency multiplier is designed and fabricated. Embedded on a circuit in a multiplier block, the system exhibits state-of-the-art, flange-to-flange efficiency of 21% at 102 GHz. The maximum output power was 32 mW, which could be further increased by scaling and integration of the device.
