Patent ID: 7625131

Claim:
An interface comprising: a pin configured to transport energy from a monolithic microwave integrated circuit to a waveguide; an assembly surrounding the pin configured to reduce energy loss as compared to a pin without the assembly surrounding the pin; wherein one end of the pin is disposed within the assembly and an opposing end of the pin is disposed within the waveguide; a wire connector directly connected to the monolithic microwave integrated circuit on one end and directly connected to the opposing end of the pin disposed within the assembly; a space defined between the pin and the assembly; wherein size of the space and size of the pin are selected to facilitate impedance transformation along the interface in order that the energy will experience a similar impedance at an end of the interface near the monolithic microwave integrated circuit as the energy experiences on the monolithic microwave integrated circuit and also experience a similar impedance at an opposing end of the interface near the waveguide as the energy experiences in the waveguide.
