Abstract: An apparatus includes an integrated circuit. The integrated circuit includes a low-noise amplifier having a first complex input impedance. The integrated circuit includes a complex attenuator coupled to an input terminal of the integrated circuit. The complex attenuator has a second complex input impedance and a first complex output impedance. The apparatus may include a matching network coupled to the input terminal of the integrated circuit. The matching network is external to the integrated circuit. The matching network may have a first real input impedance and a second complex output impedance. The second complex output impedance is matched to the second complex input impedance.

Abstract: In one aspect, an apparatus includes: a mixer to receive a radio frequency (RF) signal and downconvert the RF signal into a second frequency signal; an amplifier coupled to the mixer to amplify the second frequency signal; an image rejection (IR) circuit coupled to the programmable gain amplifier (PGA) to orthogonally correct a gain and a phase of the amplified second frequency signal to output a corrected amplified second frequency signal; and a complex filter to filter the corrected amplified second frequency signal.

CPC classification number: H03G3/3052
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.
