Abstract

The invention relates to a high-temperature superconducting receiver front-end device in space. The high-temperature superconducting receiver front-end device comprises a refrigerating machine, a vacuum dewar and a superconducting filter and a low-temperature amplifier which are arranged in the vacuum dewar. One end of the superconducting filter is fixedly arranged in the vacuum dewar through an adiabatic support structure, and the other end of the superconducting filter is connected with the low-temperature amplifier. A heat-conducting band is disposed between the superconducting filer and the low-temperature amplifier. One end of the heat-conducting band is positioned between the superconducting filer and the amplifier, and the other end of the heat-conducting band is connected with a cold head of the refrigerating machine. The superconducting filter and the low-temperature amplifier are arranged up and down. The adiabatic support structure contains an adiabatic support plate and an adiabatic strut. One end of the adiabatic strut is fixedly connected with the adiabatic support plate, and the other end of the adiabatic strut is fixedly connected with the bottom of the vacuum dewar. The heat-conducting band is multilayered copper foils. An adiabatic layer is arranged on the periphery of both the superconducting filer and the low-temperature amplifier. According to the invention, volume of the receiver front-end is minimized; stability of the receiver front-end structure and low thermal capacitance and low heat leakage of the system are also guaranteed; and performance and working stability of the receiver front-end are raised.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a high-temperature superconducting receiving front-end device for space use. Background technique [0002] In the fields of long-distance detection and space astronomy, high-temperature superconducting receiving front-ends are widely used due to their low loss and high out-of-band suppression. The high-temperature superconducting receiving front end can not only effectively improve the receiving ability and signal processing ability of the receiver, but also reduce the impact of high power on the surrounding biological environment and electronic equipment, and improve its own anti-interference ability. The existing high-temperature superconducting receiving front ends all adopt a planar installation structure, and the superconducting filter and the low-temperature amplifier are installed side by side on the cold plate, and then the cold plate is coupled to the cold head of the...
