Abstract

An integrated point-to-point microwave radio frequency unit/antenna has a housing, a microwave antenna affixed to the front face of the housing, and a microwave radio frequency transceiver electronics package within the housing. The transceiver electronics package includes a circuit board having transmitter and receiver intermediate frequency processors. The transceiver electronics package further includes a microwave transmitter and a microwave receiver, each utilizing monolithic microwave integrated circuit architecture. The signals of the microwave transmitter and microwave receiver are preferably of different frequencies and are diplexed for communication with the antenna.
