Abstract:
1. An end launcher of microwave signals with controlled electric field polarization for transitioning between an MMIC and a waveguide connection, comprising: a universal conductive housing having at least a broad wall and a major wall, at least one cavity with a platform for accommodating said MMIC and control components, having at least one feedthrough mounted in said major wall, each with one metal pin having a first end portion and a second end portion; a conductive plate with a first arm having a first axis, a first length and a first width and a second arm having a second axis, a second length and a second width defining a first broad wall and a second broad wall of said conductive plate, said first arm and second arm defining a thickness and providing an L-shape waveguide probe, one end portion of said first aim having a slot with a slot width and a slot length for the connection to the first end portion of said metal pin of the feedthrough in said universal conductive housing, said L-shape waveguide probe being aligned so that the second axis is substantially parallel to said major wall of the universal conductive housing, the distance between the second axis and said major wall being selected on the basis of frequencies of the microwave signals; a conductive universal launching adapter having a through channel with two long inner walls and two short inner walls, said two long inner walls and two short inner walls defining a cross-section of said through channel, said universal launching adapter being mounted to the major wall of said universal conductive housing; and a waveguide section with two broad inner walls and two narrow inner walls, said two broad inner walls and two narrow inner walls defining a cross-section of said through channel.
