Abstract
Apparatus and methods of manufacture for a wideband RF mixer are provided. The RF mixer includes an input, an LO input, and an output. A variable impedance tuner is disposed in an input signal path between the input port and the RF mixer, and a variable impedance tuner is disposed in an output signal path between the output and the RF mixer. The impedances of the variable impedance tuners are controllable for a particular frequency of operation with one or more digital or analog control signals.
