Abstract: An arrangement and method for hybrid beamforming includes a differential phase shifter. The phase shifter has substantially parallel elongate conductive input and output radio frequency transmission lines. A movable transverse planar conductive coupling element configured to provide capacitive coupling between itself and the input and output lines. The coupling element is slideably movable along an axis of the said input and output transmission lines.

Abstract: An integrated radio base station has an elongate structural support member and a non-conductive dielectric cover, together forming a weather-protective housing. An internal power bus and internal data bus are located within the housing. At least one functional module is provided within the housing and has a functional electronic circuit device and an antenna, a module power bus providing power to the functional electronic circuit device and a module data bus providing data to the functional electronic circuit device. The functional module further has a functional power connector coupling the module power bus to the internal power bus, and a functional data connector coupling the module data bus to the internal data bus.

Abstract: An antenna system having a quick release that removably and reliably connects a Remote Radio Unit (RRU) to an Integrated Antenna Unit (IAU), both mechanically and electronically. The RRU has an RRU connector and the antenna has an antenna connector that removably engages with and mates with the RRU connector. The system has a temporary hanging position that enables a user to connect additional electronic connections to the RRU before it is fully coupled with the antenna.
