ABSTRACT:
A transmitter/receiver basestation processing a plurality of channels in an RF band is disclosed. The transmitters and receivers of the present invention up-convert or down-convert the RF band as a whole, rather than on a channel-by-channel basis. After up-converting/down-converting to intermediate frequency, the respective channel signals are extracted/combined by means of a plurality of mixed-up or mixed-down base band carriers. The present basestation dramatically improves the efficiencies of the basestation such that the components of the basestation can be integrated on a single chip.
