ABSTRACT:
An apparatus comprising an amplifier circuit, a tuning circuit and a mixer circuit. The amplifier circuit may be configured to generate an output signal at a first node in response to an input signal received through a second node. A tuning circuit may be (i) coupled between said second node of the amplifier circuit and third node and (ii) configured to adjust an impedance presented to the third node in response to a tuning voltage. A mixer circuit may have a center tap coupled to the third node.
