A frequency conversion apparatus includes a frequency generation circuit, which is based on a first semiconductor material having a first elemental composition and is coupled to generate one or more Local Oscillator (LO) signals. The apparatus further includes a conversion circuit, which is based on a second semiconductor material having a second elemental composition different from the first elemental composition. The conversion circuit is coupled to accept an input signal in a first frequency range and to convert the input signal to an output signal in a second frequency range by mixing the input signal with the one or more LO signals.

Integrated RF-IF converter

A configurable frequency conversion device includes an up-converter, which is arranged to convert an input transmit signal to an interim transmit signal at an intermediate transmit frequency and to convert the interim transmit signal to an output transmit signal at an output frequency. A down-converter is arranged to convert an input receive signal at an input frequency to an interim receive signal at an intermediate receive frequency and to convert the interim receive signal to an output receive signal. Local Oscillator (LO) generation circuitry is arranged to generate multiple LO signals having respective LO frequencies and is coupled to drive the up- and down-converter with the LO signals, and is externally configurable to modify one or more of the LO frequencies so as to modify any of the output frequency, the input frequency, and a separation between the output and input frequencies without changing the intermediate receive and transmit frequencies.
