Abstract
A radar transmit and receive integrated microwave module with conductively cooled condenser side rails and one or more vacuum brazed fluid distribution manifold cold plates in fluid communication with the side rails. There are one or more transmit and receive modules on a cold plate. Each module includes a coolant input and a coolant output. One or more gallium nitride monolithic microwave integrated circuits are within each transmit and receive module and each include a micro heat exchanger in fluid communication with the coolant input and the coolant output of the transmit and receive module to directly cool the gallium nitride monolithic microwave integrated circuit.

A radar transmit and receive integrated microwave module comprising:
- conductively cooled condenser side rails;
- one or more vacuum brazed fluid distribution manifold cold plates in fluid communication with the side rails;
- one or more transmit and receive modules on a cold plate, each module including a coolant input and a coolant output;
- and
- one or more gallium nitride monolithic microwave integrated circuits within each transmit and receive module and each including a micro heat exchanger in fluid communication with the coolant input and the coolant output of the transmit and receive module to directly cool the gallium nitride monolithic microwave integrated circuit.
A radar module comprising:
- cooled rails;
- one or more cold plates;
- one or more transmit and receive modules on a cold plate, each transmit and receive module including a coolant input and a coolant output in fluid communication with the cooled rails;
- and
- one or more microwave integrated circuits within each transmit and receive module each including a heat exchanger for receiving coolant to directly cool the microwave integrated circuit.
A radar module comprising:
- at least one cold plate;
- at least one transmit and receive module on the cold plate, said each module including a coolant input and a coolant output;
