A low cost 77 GHz monolithic transmitter for automotive collision avoidance systems

Abstract

The design, integration and test results of a 77 GHz GaAs monolithic transmitter specifically optimized for low cost, large volume automotive collision avoidance systems is presented.Greater than +15 dBm of output power has been achieved at the output waveguide intexface across a 1 GHz bandwidth using monolithic chips exclusively. This module, due to its small size, light weight and low production cost, is a significant advance in MMW technology from traditional waveguide hybrid approaches and it now makes collision avoidance radars affordable.
