摘要
介绍了一个W频段宽带倍频器.采用反向并联二极管对结构实现宽带倍频.该倍频器输入为WR-28波导到微带过渡结构,输出为WR-10减高波导.在输入功率为5dBm时,在整个W频段输出功率为0.81±1.80dBm,二次谐波抑制度大于25dBc.该倍频器可把Ka频段的信号源扩展到W频段.
A W-band broadband frequency tripler was formed by anti-parallel Schottky-barrier diode pair. The input signal was fed in by a WR-28 wavegnide-to-microstrip transition, and the output signal was fed out by a reduced-height WR-10 wavegnide. For the input power of 5dBm, the output power was 0.81 ＋ 1.80dBm and the second harmonic rejection was greater than 25dBc in the whole W-band. This tripler can be used to extend Ka-band signal source to W-band.
