This letter presents a single chip 12 frequency multiplierMMICfor the W-band that is realized in a 100 nm metamorphic HEMT technology. To obtain the 12 multiplication factor a multiplier chain of a doubler, a tripler and a doubler has been cascaded. The circuit has a 3 dB bandwidth of 15 GHz from 85 to 100 GHz. At 94 GHz, the multiplier achieves a saturated output power of more than 1 dBm and a conversion gain of 0 dB. The suppression of unwanted harmonics is better than 30 dBc at 94 GHz and better than 24 dBc within the entire bandwidth.
