76GHz to 81GHz FMCW Radar Receiver
The WEA7681RX22G is a Zero-IF receiver for radar applications covering the 76 GHz to 81 GHz automotive band.
Overview
The WEA7681RX22G is a complete Zero-IF receiver for radar applications covering the 76 GHz to 81 GHz automotive band. The receiver integrates a Low Noise Amplifier, a down conversion mixer, a 1st order active highpass filter, a 1st order passive high pass filter and a 3rd order lowpass filter and a variable gain amplifier with digital gain control. The local oscillator chain is also integrated on the same IP. The LO accepts an input at 38 GHz to 40.5 GHz. The receiver has a dual saturation detector scheme for strong blocker detection at the mixer and the filter output. The receiver has a build-in Analog Test Bus (ATB) for complete monitoring of the bias conditions of all blocks, for FuSa. It is implemented in 22FDX FD-SOI process. The WEA7681RX22G occupies a silicon area of 1450 um x 450 um.
