Abstract :
A new configuration of a MMIC gate mixer associated with a dual-polarized patch antenna was experimentally investigated at 94 GHz for the first time. A 7 dB reduction in the LO power requirement was experimentally observed when compared to a previously used resistive mixer. The new configuration with its low pumping power can significantly simplify the design of the LO sensor chain compared to the ordinary mixer configuration which consumes 3-10 dBm per device to attain a sufficiently low conversion loss for a typical radar application.
