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.
