摘要: 本文介绍了一种微带巴伦多倍频程微波集成双平衡混频器。它是由宽带微带巴伦和二极管电桥组成。这种微带巴伦双平衡混频器显示了良好的噪声特性和隔离特性。在1-18GHz工作频率范围内,最大双边带噪声系数为8.7dB,平均双边带噪声系数约6dB;本振端一信号端、本振端一中频端隔离度均大于15dB。

Abstract: A multi-octave microstrip balun double balanced mixer has been developed. This mixer which is consisted of a broad-band balun and a diode ring exhibits extremely encouraging performance. Within the multi-octave bandwidth from 1 to 18 GHz, the average DSB noise figure is 6 dB, and the maximum DSB noise figure is 8.7 dB, and both LO-RF and LO-IF isolations are more than 15 dB. -
