Low-cost wireless millimeter wave outdoor unit (ODU)

A lightweight millimeter wave outdoor unit for mounting on an antenna to form a wireless link comprising:

• a housing that is configured for quick connect/disconnect mounting on the antenna;
• a millimeter wave transceiver board formed of ceramic material and mounted within the housing;
• a transceiver circuit formed on the millimeter wave transceiver board and having transmit and receive circuits and a local oscillator circuit and a plurality of microwave monolithic integrated circuit (MMIC) chips mounted on the transceiver board in at least transmit and receive circuits and operable at radio frequency;
• an intermediate frequency (IF) board mounted within the housing and having components forming an intermediate frequency circuit operable with the transceiver circuit and operable for receiving and forwarding signals to an indoor unit (IDU);
• a frequency synthesizer board mounted within the housing and having surface mounted components forming a signal generating circuit for generating local oscillator signals to the transceiver circuit;
• a controller board mounted within the housing and having surface mounted DC and low frequency discrete devices thereon forming power and control circuits that supply respective power and control signals to other circuits on other boards;
• circuit contact members that interconnect the circuits between the board;
• and
• a plurality of housing separator members that separate respective transceiver, controller and frequency synthesizer boards and having channelization and at least one electromagnetic interference gasket to aid in isolating any circuits on a board.
