Abstract

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.
