Abstract :
This paper presents the design and performance of a hybrid semiconductor/superconductor microwave integrated circuit (MIC) K-band channelized amplifier. The circuit combines the high frequency, high performance advantages of a cryogenically cooled GaAs PHEMT with the low loss, high Q properties of an HTSC filter and matching networks. A comparison of measured and predicted results is presented: the filter/amplifier combination has a measured noise figure of 1.8dB, with an associated gain of 7.1dB at 18.9GHz.
