An Integrated Receiver Frontend for a 94 GHZ Dual Polarization Radar

A dual channel receiver frontend for a 94 GHz radar with dual polarization capabilities is discribed. Ihe frontend consists of polarizer, circulator, filters, STC PIN-diode switches, balanced mixers and power divider for the LO and is built, except for the polarizer, using E-plane techniques. In this way, an integrated, canpact and very rugged frontend has became possible.
