摘要：

An integrated downconverter for active antenna arrays is presented. From 5.125 GHz to 5.875 GHz the downconverter shows more than 20 dB conversion gain and a noise figure of less than 3.8 dB with a minimum of 3.3 dB. Input 1 dB compression point is -18 dBm. Image rejection better than 35 dB is achieved using an integrated lumped-element bandpass filter. A switchable symmetric input amplifier is proposed to calibrate amplitude and phase errors without degrading the noise figure.
