而且在超外频的时候，要注意到它是四倍频（quad-pumped）的。说到这个，很多人会联想到DDR（双倍数据流，double data rate）的双倍频，部份内存和显卡内存都用这种模式，达到2倍的传输率...

The millimeter-wave quadrupler is realized by HMC283, which is actually a MMIC amplifier. It can be designed as quadrupler by offsetting its operating point of the first FET to pinchoff area.
毫米波四倍频器部分采用HMC283单片,它由四级放大器组成,将其第一级的工作点偏置到夹断区,使其输出为半个正弦波形,即可产生丰富的偶次谐波,通过后三级的放大,最后由微带到波导转换接口输出。
