Abstract: A radio receiver and method of operating the same are disclosed. In one embodiment, the radio receiver may include a RF receive path configured to convey a first radio signal within a first band to a radio tuning circuit. The RF receive path may be controllable using a first AGC circuit. The radio receiver may also include a loop-through path configured to convey a second radio signal within a second band between an input and an output of the radio receiver. The second band may be different from the first band. The loop-through path may be controllable using a second AGC circuit.

Abstract: A radio frequency (RF) receiver front end includes an RF attenuator for receiving an RF input signal and a low noise amplifier (LNA). In one form, the LNA provides a differential output signal and includes a first polarity amplifier and a plurality of second polarity amplifiers. The first polarity amplifier has an input terminal coupled to the output of the RF attenuator, an output terminal for providing a first component of the differential RF output signal, and has a first input impedance. Each of the plurality of second polarity amplifiers has an input terminal coupled to the output of said RF attenuator, and an output terminal. The output terminals of said plurality of second polarity amplifiers are coupled together and form a second component of the differential RF output signal. Each of the plurality of second polarity amplifiers has a second input impedance higher than the first input impedance.
