ABSTRACT:
Apparatus for boosting the signal between a cell phone (14) and a cell site (16), which includes an amplifier (64) that continually operates at a fixed gain. A power detector (72) controls an attenuator (62) that can be switched to pass the amplified signal through an attenuator (74) of moderate resistance, or through an attenuator (60) of zero resistance so the power output is boosted within the limits allowed under cell phone system standards.
