Abstract

In this work, a x12 frequency multiplier chain has been developed in a 250-nm InP HBT technology for operation in the WR3.4 frequency band. The multiplier chain is composed of three frequency multipliers: a V-band frequency tripler, a D-band frequency doubler, and a WR3.4 frequency doubler. The V-band cascode frequency tripler exhibited a maximum output power of 0.83 dBm with a bandwidth of 59 - 72 GHz, while the D-band bootstrapped Gilbert-cell frequency doubler showed a maximum output power of 6.13 dBm with a bandwidth of 140 - 164 GHz. With the WR3.4 push-push frequency doubler, a maximum output power of 0.5 dBm was obtained with a bandwidth of 278 - 325 GHz. The fully integrated 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 131mW.
