摘要

This paper presents a silicon based beamformer chip for multi-beam satellite communication phased array. The chip uses SiGe technology to integrate 32 phase-shifting channels, each with a power consumption of less than 29mW. In the range of 10GHz to 13GHz, the measured noise figure is 1.7-2.0dB, the gain is greater than 21 dB, the RMS gain error and phase error are更多
