Abstract

This paper describes two-stage InP-based cryogenic broadband amplifier with very low noise for the frequency band 1.5-4.5 GHz. For a band of 2-4 GHz at 15 K the measured gain is 30.0/spl plusmn/2 dB and a noise temperature below 5 K. The total DC power consumption of the amplifier is 6.8 mW.
低温2-4 GHz超低噪声放大器
本文介绍了一种基于两级inp的超低噪声1.5 ~ 4.5 GHz频段低温宽带放大器。对于2-4 GHz频段,在15k时,测量到的增益为30.0/spl plusmn/ 2db,噪声温度低于5k。放大器的总直流功耗为6.8 mW。
