A radio transceiver station avoids the problems of prior devices that either do not use multi-beam antennas or use multi-carrier power amplifiers, permitting signals from several transceivers to be selectively directed to one antenna lobe with low loss. The radio transceiver station includes an antenna system having a plurality of beams, a plurality of radio transmitters, each radio transmitter including a base band part and a radio frequency part having a single-carrier radio frequency power amplifier, a plurality of filters that are respectively connected to the plurality of radio transmitters and that are tunable to respective carrier signals generated by respective radio transmitters, and a switch matrix for connecting selected ones of the filters to the antenna system such that carrier signals generated by the transmitters and amplified by the single-carrier radio frequency power amplifiers can be radiated through selected beams. Each transmitter can be connected to each antenna beam independently of each other transmitter.
