Abstract
Frequency conversion circuitry has an input node for receiving an input signal at a first frequency and an output node for producing an output signal at a second frequency different from the first frequency. A mixer circuit is responsive to the input signal for producing a signal at the second frequency. A step down impedance transformation circuit is coupled between the input node and an input of the mixer circuit for providing input impedance of the mixer circuit lower than impedance at the input node. An amplifier circuit is coupled between an output of the mixer circuit and the output node for amplifying the signal at the second frequency produced at the output of the mixer circuit. The mixer circuit is configured for providing input impedance of the output amplifier lower than the impedance at the input node.
