Abstract
Embodiments of an Antenna and Filter Unit (AFU) for an Advanced Antenna System (AAS) are disclosed herein. In one embodiment, an AFU for an AAS comprises a first unit and a second unit. The first unit comprises a 1:N power splitter comprising an input coupled, directly or indirectly, to an antenna port of the AFU and N outputs, where N≥2. The first unit also comprises N first board-to-board type connectors electrically connected to the N outputs of the 1:N power splitter, respectively. The second unit comprises N second board-to-board type connectors configured to be electrically coupled to the N first board-to-board type connectors, respectively, and N antenna elements coupled, directly or indirectly, to the N second board-to-board connectors, respectively. By positioning the 1:N power splitter prior to the N first and N second board-to-board type connectors, input power at each of the board-to-board type connectors is reduced, which thereby reduces Passive Intermodulation.
