Abstract

We have developed an X-band low noise figure (NF) T/R switch-module using a superconducting T/R switch. The superconducting T/R switch was realized by combining a six-port network, two impedance transformers and two varactor diodes. The six-port network consists of oneλ/4 transmission line, two λ/2 transmission lines and one 3λ/4 transmission line. For each λ/2 transmission line, a single varactor diode was connected to the center of a given λ/2 transmission line by using one of the aforementioned impedance transformers. The superconducting T/R switch was fabricated using a high-Tc superconducting material called YBCO. An insertion loss of 0.3 dB was measured in Rx mode. By combining the superconducting T/R switch with a limiter and a low noise amplifier (LNA), a low NF T/R switch-module was designed. Measurements performed at X-band show an NF of 0.7 dB, which confirms the design procedure of a low NF T/R switch-module.

采用超导T/R开关的x波段低噪声图T/R开关模块
我们利用超导T/R开关开发了一种x波段低噪声系数(NF) T/R开关模块。超导收发开关由一个六端口网络、两个阻抗互感器和两个变容二极管组成。六端口网络由一条λ/4传输线、两条λ/2传输线和一条3λ/4传输线组成。对于每条λ/2传输线,一个变容二极管通过使用上述阻抗变压器之一连接到给定λ/2传输线的中心。超导T/R开关是用高tc超导材料YBCO制造的。在Rx模式下测量到0.3 dB的插入损耗。将超导T/R开关与限幅器和低噪声放大器(LNA)相结合,设计了一个低NF T/R开关模块。在x波段进行的测量显示NF为0.7 dB,这证实了低NF T/R开关模块的设计过程。
