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. |
