This paper presents a single-chip 60 GHz to 120 GHz frequency multiplier chain based on 0.1 µm GaAs mHEMT. The MMIC can deliver 3 to 5 dBm of output power from 110 GHz to 130 GHz with 2 dBm input power and consumes only 65 mW of DC power. The signal at the fundamental frequency is suppressed more than 20 dB over the band of interest. The impedance matching networks are realized using coupled transmission lines.
