This work presents a x12 frequency multiplier chain operating in the WR3.4 frequency band based on a 250-nm InP HBT technology. The multiplier chain is composed of a V-band cascode tripler, a D-band bootstrapped Gilbert-cell doubler, and a WR3.4 push-push doubler. The fabricated multiplier chain exhibited a saturation output power of 1.6 dBm at 300 GHz and a peak conversion gain of -3.6 dB at 3.5-dBm input power. The circuit operated over a frequency range of 246 - 318 GHz with up to 4.3-dB in-band output power variation. The total DC power consumption was 131 mW.
