Integrated microwave modules—A prospectus

Applications of monolithic and hybrid semiconductor circuit technologies to microwaves are discussed from a semitechnical and economic viewpoint. Technical feasibility of performing nearly all functions through millimeter waves is foreseen. Economic success, however, is less tangible and depends mainly on two factors; the willingness of systems people to trade increased initial cost for greatly decreased maintenance cost and the magnitude of the requirements for electronically steered antennas. The author´s estimates of the business potential are discussed.
