We demonstrate the circuit concept and performance of a broadband six-fold frequency multiplier for the W-band. The MIMIC, realized in a 100 mum metamorphic HEMT technology, combines an active single-ended to differential converter with balanced tripler and doubler stages. The novel doubler stage design employs a cascode topology. The sixtupler achieves a saturated output power of over 7 dBm and a conversion gain of more than 6 dB in a 3-dB-bandwidth of 78 to 104 GHz, with in-band contributions of unwanted harmonics staying below -25 dBc to ensure spectral purity.
