220–265GHz Active ×6 Frequency Multiplier MMIC with InP HEMT Technology

A 220–265 GHz ×6 active frequency multiplier MMIC is presented in this paper. The MMIC was fabricated in 80-nm-gate InP HEMT technology. The frequency multiplier consists of a frequency tripler, 120-GHz amplifier, frequency doubler, and 240-GHz amplifier. The frequency multiplier provides more than 0-dBm output power in the 220–265 GHz region with the peak output power of approximately 5 dBm at around 250 GHz.
