Abstract: A phase shifter assembly, suitable for a base station antenna, includes a main printed circuit board with opposing first and second primary sides. The main printed circuit board has a plurality of radio frequency (RF) transmission paths on the first primary side and a plurality of RF transmission paths on the second primary side. The phase shifter assembly also includes a first wiper arm rotatably coupled to the main printed circuit board and electrically coupled to the plurality of transmission paths on the first primary side of the main printed circuit board; and a second wiper arm rotatably coupled to the main printed circuit board and electrically coupled to the plurality of transmission paths on the second primary side of the main printed circuit board. Rearwardly extending phase shifter assemblies that are oriented perpendicular to a plane defined by a reflector within a base station antenna are also provided.

Abstract: The present disclosure describes a phase shifter assembly adapted for mitigating internal passive intermodulation within a base station antenna. The phase shifter assembly may include a mounting base formed of a non-metallic material; a first main printed circuit board and a second main printed circuit board attached to the mounting base, wherein each of the main printed circuit boards comprises a plurality of radio frequency transmission paths; a first wiper arm rotatably coupled to the first main printed circuit board and electrically coupled to at least some of the plurality of transmission paths; and a second wiper arm rotatably coupled to the second main printed circuit board and electrically coupled to at least some of the plurality of transmission paths on the second primary side of the main printed circuit board. Base station antennas adapted for mitigating internal passive intermodulation are also described.
