This paper presents a X4 frequency multiplier MMIC realized in the IAF 50 nm mHEMT technology. It consists of two cascaded frequency doublers followed by an amplifier and was designed for an output frequency range from 70 to 82.5 GHz. This corresponds to a bandwidth of 12.5 GHz or 16.4 %. The MMIC achieves a relatively flat output power of 9.5 dBm with a variation of only ± 0.4dB. The unwanted harmonics were suppressed in the output spectrum by more than 52 dBc.
