给出了一种新的k_a波段鳍线平衡混频器及其电路设计。它和波导混频器有相同的性能,并具有电路简单、加工方便、工作频带宽等优点。在完全采用国产软性基片和混频二极管芯下,得到了良好的性能:36.5GHz上变频损耗达5.1dB,3dB带宽为1500MHz,信号口驻波小于2.0。
A new k_a band fin balance mixer and its circuit design are given. It has the same performance as the waveguide mixer, and has the advantages of simple circuit, convenient processing and wide working band. In the full use of domestic soft substrate and mixing diode core, get a good performance: 36.5GHz up conversion loss of 5.1dB, 3dB bandwidth is 1500MHz, signal port standing wave is less than 2.0.
