Microwave transmit/receive assembly

摘要

A microwave transmit/receive assembly comprising a microwave integrated circuit MIC module mounted on a printed circuit board PCB, and a microwave filter block E. The MIC module comprises a metal baseplate B having a dielectric layer carrying conductive microstrip tracks forming microwave integrated circuitry for processing transmitted and received signals. The printed circuit board carries additional circuitry and the MIC module includes stripline-to-waveguide transitions for coupling signals between the MIC circuits and waveguide interfaces of the filter block. The filter block may be an E-plane filter block and the PCB has an aperture 5 over which the MIC is located and through which the filter block projects.
