1-18GHz微帶巴倫雙平衡混頻器
A 1-18GHz MICROSTRIP BALUN DOUBLE BALANCED MIXER
-
摘要: 本文介紹了一種微帶巴倫多倍頻程微波集成雙平衡混頻器。它是由寬帶微帶巴倫和二極管電橋組成。這種微帶巴倫雙平衡混頻器顯示了良好的噪聲特性和隔離特性。在1-18GHz工作頻率范圍內(nèi),最大雙邊帶噪聲系數(shù)為8.7dB,平均雙邊帶噪聲系數(shù)約6dB;本振端一信號端、本振端一中頻端隔離度均大于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. -
