Phase Shifter Design Improvements

An improved phase shifter assembly is provided. The phase shifter assembly may comprise first and second sub-assemblies with certain common actuating elements. In one example, a first phase shifter sub-assembly is provided, the first phase shifter sub-assembly including a first phase shifter carrier, a first phase shifter printed circuit board mounted on the first phase shifter carrier, a first wiper printed circuit board coupled to an input of the first phase shifter printed circuit board and having at least a first end coupled to transmission lines on the first phase shifter printed circuit board, and at least one wiper support mechanically coupling the first wiper printed circuit board to the first phase shifter printed circuit board. A second phase shifter is similarly provided. Common actuating elements may include a pivot arm and a throw arm. The pivot arm may be rotatably mounted in the phase shifter assembly and be configured to engage a wiper support of at least one of the first and second phase shifter sub-assemblies. The throw arm may be mounted such that when the throw arm is moved linearly, the pivot arm rotates around a pivot.
