A Low Power Ka-Band Receiver Front-End in 0.13μm SiGe BiCMOS for Space Transponders

In direct-to-earth or deep space communication links, providing energy is very expensive and therefore it is essential for the link receiver to consume very low power while providing high sensitivity and gain. This paper presents a low power 0.13µm SiGe Ka-band receiver where the current sharing technique is used to reduce the power consumption of the front-end to 5.8mW while providing 17dB of RF-IF conversion gain, double side band noise figure less than 8.9dB across the bandwidth, and -1dB input referred compression point of - 25dBm.
