Patent ID: 7024231

Claim:
A booster system in a cellular phone base station comprising: a plurality of boosters each of which having: a plurality of power amplifiers, each of which configured to receive a signal provided by a corresponding transceiver unit coupled to said booster system; a booster hybrid combiner coupled to said plurality of power amplifiers, said hybrid combiner configured to combine the signals generated by each of said power amplifiers; and a VSWR sensor configured to sense a voltage standing wave ratio at an output port of said booster system, wherein said booster system maintains a first, a second and a third booster, each configured to receive a first and second radio frequency signal such that the output of said first booster is coupled to a first input of a booster system hybrid combiner and the output of said second booster is coupled to a second input of said booster system hybrid combiner and the output of said third booster is coupled to a third input of said booster system hybrid combiner, said booster system hybrid combiner providing via its output port a combined signal of six carrier frequencies.
