A wireless LAN comprises an access point and plural mobile communications devices requiring data communication with the access point. Extension of the frequency hopping pattern associated with the uplink can compensate for a power imbalance between the uplink and the downlink by improving the gain of the uplink. The balanced integrated circuit coupling couples the plurality of power amplifiers to the up-conversion module such that the power amplifiers amplify the up-converted signal to produce a plurality of amplified radio frequency signals. A connecting element has a shaft passing through a central aperture in the intermediate element, thus also extending through the aperture in the arm.
