Design of HTS receiver with CMOS low noise amplifier

摘要

For realizing a single chip HTS integrated microwave receiver, a superconducting slot antenna and a Si-CMOS low noise amplifier (LNA) combined with a broad band matching circuit composed of coplanar waveguide (CPW) meanderline resonators has been designed and tested. We have been studying a new design theory for the broadband impedance matching circuit for the small antenna, which is based on the conventional design theory of n-pole bandpass filter. Moreover we also study the theory of impedance matching circuit for a CMOS-LNA. Then, we also present the simulated performances of CMOS-LNA and experimental result of a folding slot antenna with broadband matching circuit made of the YBCO film.
