Abstract
A single-ended 77/79 GHz monolithic microwave in-
tegrated circuit (MMIC) receiver has been developed in SiGe HBT
technology for frequency-modulated continuous-wave (FMCW)
automotive radars. The single-ended receiver chip consists of the
first reported SiGe 77/79 GHz single-ended cascode low noise
amplifier (LNA), the improved single-ended RF double-balanced
down-conversion 77/79 GHz micromixer, and the modified dif-
ferential Colpitts 77/79 GHz voltage controlled oscillator (VCO).
The LNA presents
