A compact manufacturable 76-77-GHz radar module for commercial ACC applications

摘要: The design and measured results of a single-substrate transceiver module suitable for 76-77-GHz pulsed-Doppler radar applications are presented. Emphasis on ease manufacture cost reduction commercial millimeter-wave systems is employed throughout as parameter. importance using predictive modeling techniques in understanding the robustness circuit stressed. Manufacturing that conform to standard high-volume assembly constraints have been used. packaged module, including three waveguide ports intermediate-frequency output, measures 20 mm/spl times/22 times/8 mm. implemented discrete GaAs/AlGaAs pseudomorphic high electron mobility transistors (pHEMTs), GaAs Schottky diodes, varactor well p-i-n pHEMT monolithic microwave integrated circuits mounted low-cost 127-/spl mu/m-thick glass substrate. A novel microstrip-to-waveguide transition described transform planar microstrip signal into launch. with quasi-optical antenna. performance both component parts complete described.
