摘要

提出了一种具有8个接收模块的3ghz频段高tc超导(HTS)多通道接收单元。每个模块由一个小型高温超导滤波器和一个冷却低噪声放大器(LNA)组成。高温超导滤波器由多个数字间发夹微带线谐振器组成。模块尺寸实现22×29.5 mm，高温超导多通道接收单元的真空室尺寸实现152×180×119 mm。实现了此类模块产品的最小尺寸。HTS滤波器的插入损耗小于0.1dB。结果表明，HTS多通道接收单元在77 K时的噪声温度测量结果比仅LNA在室温下的噪声温度提高到不到1/3。

3 GHz band HTS multichannel receiving unit with 8 modules

We have proposed an 3 GHz band High-Tc superconducting (HTS) multichannel receiving unit with 8 receiving modules. Each module consists of a small HTS filter and a cooled low noise amplifier (LNA). The HTS filter consists of a number of inter-digital hairpin microstrip line resonators. The module size realize 22×29.5 mm and vacuum chamber size of the HTS multichannel receiving unit realize 152×180×119 mm. It realizes the smallest size as such module products. Insertion loss of the HTS filter was smaller than 0.1dB. As a results, measured results of noise temperature at 77 K for the HTS multichannel receiving unit improved to less than 1/3 as compared with the noise temperature of only LNA at room temperature.
