英文摘要	This letter presents a novel L-band cryogenically- coolable low noise amplifier applied in radio astronomical receivers. This amplifier can be operated at temperatures of 300K to 4K. Its noise temperature is less than 6K at 20K physics temperature in the frequencies of 1.2 similar to 1.8 GHz. Over 30 dB gain, more than 10 dB input/output return loss and better than +/- 0.75 dB gain flatness are achieved; Especially, this LNA achieves extremely high large signal performance. Its three order intercepts and 1 dB compressed power referred to output is up to 25.5 dBm and 15 dBm, respectively. (C) 2017 Wiley Periodicals, Inc.
