摘要

研制了一种20 GHz频段135 K (NF=1.66dB)低噪声、增益38 dB的HEMT放大器。这是通过极低损耗的输入电路，精确的器件表征方法，带线调谐器和紧凑的冷却系统实现的。放大器被冷却到-55°C的珀尔提尔冷却装置，仅消耗60瓦。

A 20 GHz Peltier-Cooled Low Noise HEMT Amplifier

A 20 GHz band 135 K (NF=1.66dB) low-noise HEMT amplifier with 38 dB gain has been developed. This was achieved by extremely low-loss input circuits, accurate device characterization method with a strip line tuner and a compact cooling system. The amplifier is cooled to -55°C by a Peltier-cooling unit which consumes only 60 watts.
