1. A microwave monolithic integrated circuit (MMIC) package comprising:

  • a single MMIC including a plurality of pads forming chip input and output pads and DC pads;

    a base plate that is matched as to its coefficient of thermal expansion (CTE) with the MMIC;

    a solder preform contained on the base plate, said MMIC being mounted on the solder preform; and

    a chip cover having openings and covering the MMIC to form a MMIC package that can be automatically picked and placed, wherein the base plate and chip cover are configured with respective portions that engage each other and such that the chip input and output and DC pads on said MMIC are directly exposed to atmosphere through openings of the chip cover for wire and ribbon bonding, wherein the base plate and MMIC are secured together by a solder flow process from said solder preform.
