GaAs monolithic microwave integrated circuits are reviewed focusing on analytical and experimental work to improve array performance and reliability while reducing the cost. Monolithic array technology is equally applicable to communications and radar systems. In radar applications both transmit and receive functions at the elemental level require a transmit/receive module's physical size to be compatible with 1/2 wave length element spacing. For communication applications, separate aperture are used for transmit and receive to ensure sufficient isolation for full duplex operation. Radar transmitter chains are capable of operating with a saturated power output stage which helps to increase efficiency and minimize DC power. Communication systems place severe linearity constraints on the transmitters and receivers which requires the power amplifier to operate in an ultra-linear fashion.
