本文介绍了一种单片× 12倍频的w波段MMIC，该MMIC采用100 nm变质HEMT技术实现。为了得到× 12的乘法系数，一个倍频器、一个三倍频器和一个倍频器的乘法器链被级联。该电路在85至100 GHz范围内具有15 GHz的3db带宽。在94 GHz时，该倍增器的饱和输出功率超过1 dBm，转换增益为0 dB。在94ghz时，对多余谐波的抑制优于30dbc，在整个带宽内，对多余谐波的抑制优于24dbc。
This letter presents a single chip × 12 frequency multiplier MMIC for 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.
