Patent ID: 7130661

Claim:
An apparatus for forming a beam in a base station, comprising: a plurality of channel cards for processing and outputting signals to be transmitted to each channel; a signal synthesizer/distributor for synthesizing the signals from the channel cards and compensating phases of the signals; at least one channel controller for controlling beams of the signals from the signal synthesizer/distributor according to a demand of a mobile communication terminal, and outputting the controlled beam signals; at least one middle frequency generating block for receiving the signals from the at least one channel controller and synthesizing the signals in each frequency to generate middle frequency signals; at least one transmitter for converting the middle frequency signals received from the at least one middle frequency generating block into signals in a transmitting band; a Radio Frequency Block (RFB) for amplifying the signals from the at least one transmitter into signals in an output band and controlling phases of transmitting and receiving signals; and an antenna connection block for switching the amplified signals to corresponding antennas of the RFB so that beams can be generated.
