This paper presents a miniaturized high performance high temperature superconducting (HTS) microwave receiver front-end subsystem, which uses a mini stirling cryocooler to cool a high selective HTS filter and a low noise amplifier (LNA). The HTS filter was miniaturized by using specially designed compact resonators and fabricating with double-sided YBCO films on LAO substrate which has a relatively high permittivity. The LNA was specially designed to work at cryogenic temperature with noise figure of 0.27dB at 71K. The mini cryocooler, which is widely used in infrared detectors, has a smaller size (60mm×80mm×100mm) and a lighter weight (340g) than the stirling cryocoolers commonly used in other HTS filter subsystem. The whole front-end subsystem, including a HTS filter, a LNA, a cryocooler and the vacuum chamber, has a size of only φ120mm×175mm and a weight of only 3.3kg. The microwave devices inside the subsystem are working at 71.8K with a consumed cooling power of 0.325W. The center frequency of this subsystem is 925.2MHz and the bandwidth is 2.7MHz (which is a fractional bandwidth of 0.2%), with the gain of 19.75dB at center frequency and the return loss better than −18.11dB in the pass band. The stop band rejection is more than 60dB and the skirt slope is exceeding 120dBMHz −1 . The noise figure of this subsystem is less than 0.8dB. This front-end subsystem can be used in radars and communication systems conveniently due to it’s compact size and light weight.
