76 GHz to 81 GHz FMCW Radar Transmitter
The WEA7681TX22G is a transmitter chain for radar applications covering the 76 GHz to 81 GHz automotive band.
Overview
The WEA7681TX22G is a transmitter chain for radar applications covering the 76 GHz to 81 GHz automotive band. The transmitter chain consists of a programmable phase shifter, two frequency doubler stages and a 3-stage power amplifier. All the stages are supported by programmable bias current circuitry. The transmitter has a dual power detector scheme for optimum transmit power management and has a build-in Analog Test Bus (ATB) for complete monitoring of the bias condition of all whole IP for FUSA. It is implemented in 22FDX FD-SOI process. The WEA7681TX22G occupies a silicon area of 1500 um x 460 um.
