MM-Wave Modules for Short Range Radar Systems

High performance mm-wave miniature module for short range Doppler and FMCW radar sensors has been developed. The module is shown in fig.1. It includes: circular polarization diplexer, monolithic GaAs balanced mixer, power divider, and Gunn diode VCO. The low 1/f noise mixer diodes and high performance oscillator enhance the detection sensitivity at low IF frequency and circular polarization waveform improves reception ability for various radar targets. Module has been designed to be used in automotive, industrial and military sensing applications, has low cost and suitable for mass production.
