摘要
本文介绍了一种由低次级联形式构成的W波段宽带六倍频器。输入信号先经过MMIC得到二倍频,再由反向并联二极管对平衡结构实现宽带三倍频,从而将Ku波段信号六倍频到W波段。该倍频器的输入端口为玻璃绝缘子同轴转换接头,输出为WR-10标准矩形波导结构。仿真结果表明当输入信号功率为20dBm时,三倍频器在整个W波段的输出三次谐波功率为4.5dBm左右,变频损耗小于17dB。该设计可以降低毫米波设备的主振频率,扩展已有微波信号源的工作频段。
A broadband frequency multiplier in W-band has been realised by the way of low-cascading. The input signal is doubled by a MMIC first and then tripled by a balance circuit which is formed by anti-parallel Schottky-Barrier diode pair, the signal of Ku-band has been extended to W-band. Its input signal is fed in by the glass insulator, the output signal is fed out by a WR-10 waveguide. While the input signal power is 20dBm, simulation shows the third harmonic output of the tripler is about 4.5 dBm, and the conversion loss is lower than-14.3dB. It can reduce the frequency of main vibration equipment, expanding microwave signal source' s working frequency.
