ABSTRACT:
A signal strength indicator circuit that includes a first amplifier configured to receive a first input signal from a first mixer and a second input signal from a second mixer;. The circuit also includes a second amplifier configured to receive a first set of differential inputs from the first amplifier. The circuit further includes a third amplifier configured to receive a second set of differential inputs from the second amplifier stage. Even further, the circuit includes an output port for emitting an output signal that is a rectified combination of the first input signal and the second input signal. Also, a method of processing signals input into a signal strength indicator circuit.
