摘要： A lightweight millimeter wave outdoor unit includes a lightweight housing with a heat sink and mounting member configured for mounting on the antenna to form a wireless link. A millimeter wave transceiver board is formed of ceramic material and mounted within the housing. It includes a millimeter wave transceiver circuit that has microwave monolithic integrated circuit (MMIC) chips and operable with the transmit and receive boards. An intermediate frequency (IF) board has components forming an intermediate frequency circuit operable with the millimeter wave transceiver circuit. A frequency synthesizer board has a signal generating circuit for generating local oscillator signals to the transceiver circuit. A controller board has 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. A quick connect/disconnect assembly is operative with the housing for allowing the housing to be rapidly connected and disconnected to the antenna circuit contact members interconnect circuits between boards.

摘要： A receiver is operable at microwave frequencies and includes a substrate and waveguide-to-microstrip transition formed on the substrate for receiving microwave radio frequency (RF) signals. Surface mounted receiver components are interconnected with microstrip formed on the substrate and receive the RF signals from the waveguide-to-microstrip transition and convert the signal to an intermediate frequency (IF) for further processing. The surface mounted receiver components include a mixer circuit that receives a local oscillator (LO) signal and RF signal to produce the IF signal. A diplexer circuit and a temperature compensated attenuator circuit received the IF signal from the mixer and attenuates the IF signal to provide high signal linearity and high order modulation.
