1. An integrated antenna and filter unit for wireless communications, the integrated antenna and filter unit comprising:
a filter portion configured to receive radio frequency, RF, signals, the filter portion including:
at least one filter configured to filter the RF signals to generate filtered RF signals; and
a plurality of filter pins configured to output filtered RF signals;
an antenna portion securable to the filter portion, the antenna portion including:
a printed circuit board, PCB, including a plurality of conductor traces each mateable with a corresponding one of the plurality of filter pins to electrically couple the plurality of filter pins directly to corresponding ones of the plurality of conductor traces on the PCB, the electrical couplings from the filter portion (14) to the antenna portion (12) are performed without mechanical connectors; and
a plurality of antennas securable to the PCB, the plurality of antennas being electrically coupled to the plurality of conductor traces.
