Abstract: Aspects of the present disclosure involve a system and method for generating noise waves at millimeter wave frequencies. A noise source generator is designed to be connected to a crystalline structure for efficient heat transfer and compatibility with millimeter wave receivers. The use of crystalline structure coupled to the noise source generator allows heat from a biasing device, such as a diode, to be carried away such that the diode is able to generate noise waves while being reversed biased without compromising the device. In another embodiment, the noise source generator includes the use of a backshort transmission line with vias that is connected to the biasing device for heat transfer from the biasing device to the backshort.

Abstract: A directional coupler assembly includes a waveguide housing. The waveguide housing has a first segment and a second segment. A first waveguide port and a second waveguide port are disposed on opposite sides of the waveguide housing. A third waveguide port is disposed on a third side of the waveguide housing, the third waveguide port being disposed substantially orthogonal to the first waveguide port and the second waveguide port. A main coupler board is disposed between the first segment and the second segment and communicatively couples the first waveguide port, the second waveguide port and the third waveguide port.
