本文介绍了一种用于平方公里阵列的GaAs双环负反馈低噪声放大器(LNA)。讨论了Transformer非理想性对LNA性能的影响。LNA在0.6 ~ 1.6 GHz范围内具有0.5 dB的噪声系数和-10 dB的输入回波损耗。
A GaAs dual-loop negative-feedback low-noise amplifier (LNA) designed for the square kilometre array is presented. Effects of transformer non-idealities on LNA performance are discussed. The LNA has 0.5 dB noise figure and -10 dB input return loss from 0.6 to 1.6 GHz.
