| Abstract: | In this paper we present a new design of Ku-band cryogenic low-noise amplifier(LNA) using interdigital capacitance microstrip structure and improved encapsulation technology.The influence of isolators to LNA is analysed.At ambient temperature about 77K,LNA achieves performance that noise factor is less than 2.0dB,reflection coefficient is less than-17dB and gain is about 10dB. |
