Abstract:
An arrangement for implementing transceiver operation at a base station, the arrangement comprising a power amplifier for amplifying signals to be transmitted, and a first receiver amplifier for amplifying received signals, wherein the power amplifier in the arrangement is a multifrequency amplifier, and that the arrangement comprises:in different sectors at least two transmitter units for generating signals at different frequencies, connected to the same multifrequency amplifier; a filter structure comprising as filters at least two different transmitter filters and at least two different receiver filters for filtering signals to be transmitted and received; in different sectors at least two antennas for transmitting and receiving signals, and at least two antenna cables, each antenna being connected with its antenna cable to at least one transmitter filter and to at least one receiver filter in the filter structure; a filter unit for filtering further the received signals; a first receiver amplifier connected to at least two sector-specific receiver amplifiers, and a separate cable for transmitting signals between the multifrequency amplifier and, the filter unit, between the filter unit and the filter structure, and between the filter unit and the first receiver amplifier.
