A compact broadband balanced frequency doubler with a novel integrated balanced FET is presented. The MMIC operates at second harmonic output frequencies from 128 to 220GHz with a maximum output power of 1.8dBm at 154GHz and an input power of 9dBm. Due to the balanced topology the MMIC is able to provide second harmonic output power over the entire G-band (140 to 220 GHz) using only a single 4-finger device. The MMIC is realized in a metamorphic HEMT technology with 35 nm gate-length for convenient integration into multifunctional MMICs.
