Abstract

A superconducting 7.3-GHz two-pole microstrip bandpass filter and a GaAs low-noise amplifier (LNA) were combined into a hybrid circuit and characterized at liquid nitrogen temperatures. This superconducting/semiconducting circuit's performance was compared to that of a gold filter/GaAs LNA hybrid circuit. The noise figure characteristics of the superconducting filter/LNA hybrid circuit when compared to the gold filter/LNA hybrid circuit showed an improvement of 2.1 dB at 77 K. The gain characteristics showed an improvement of 0.5 dB for the high-temperature superconductor (HTS) filter hybrid over the gold hybrid at 77 K.<>

YBaCuO超导滤波器/GaAs低噪声放大器混合电路的性能

将超导7.3 ghz双极微带带通滤波器和砷化镓低噪声放大器组合成混合电路，并在液氮温度下进行了表征。该超导/半导体电路的性能与金滤波器/砷化镓LNA混合电路的性能进行了比较。与金滤波器/LNA混合电路相比，超导滤波器/LNA混合电路的噪声系数特性在77 K时提高了2.1 dB。在77 k时，高温超导体(HTS)杂化滤波器的增益特性比金杂化滤波器提高了0.5 dB。
