Patent abstract

A mobile terminal senses transmitted power in a Gallium Arsenide (GaAs) circuit. The GaAs circuit provides a steady reference voltage through the use of an operational amplifier and feedback circuit. The operational amplifier drives the bases of two transistors to create balanced signals that are then used by a detection circuit.
