Abstract

Abstract: This article presents a 130 nm SiGe BiCMOS four‐channel satellite communication receiver. Phased‐array system has become the optimal solution for satellite communication due to the electrical steering nature. In order to obtain wider bandwidth, higher precision of phase shift and smaller chip size, an improved quadrature network and a phase compensation technique are proposed in this article. Each channel consists of a cascade low noise variable gain amplifier with a high Q value inductor and an active vector synthetic phase shifter. The measurement results show that the receiver consumes only 193 mA current under 1.6 V supply voltage. The chip can achieve a gain of more than 23 dB (including synthesizer losses) from 19 to 23 GHz. From 17.5 to 23 GHz, the RMS phase shifting accuracy and attenuation accuracy are less than 2.7° and 1.1 dB, respectively. The noise figure and the gain variation are less than 2.3 dB and ± 1.5 dB, respectively. The total chip area is 3.5 × 1.8 mm 2 .
