Abstract :
The design, integration and testing of a 77-GHz GaAs monolithic transmitter specifically optimized for low-cost, large-volume automotive collision avoidance systems are reported. Greater than +15 dBm of output power has been achieved at the output waveguide interface 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 MM-wave technology from traditional waveguide hybrid approaches and it now makes collision avoidance radars affordable.<>
