A system, method, and electrical circuit comprises a LNA signal line path comprising a LNA and a first signal mixer operatively connected to the LNA. The circuit further comprises an attenuator signal line path comprising an attenuator and a second signal mixer operatively connected to the attenuator; a radio frequency (RF) power detector operatively connected to an output of each of the LNA and the attenuator, wherein the RF power detector is adapted to vary a front end power gain of the electrical circuit; and logic circuitry operatively connected to the RF power detector, wherein the logic circuitry is adapted to (i) select transmission of a signal through only one of the LNA signal line path or the attenuator signal line path, and (ii) output the selected signal.
