An integrated circuit is described. The integrated circuit includes millimeter-wavelength transceiver circuitry. The millimeter-wavelength transceiver circuitry includes a local oscillator that generates a millimeter-wavelength oscillator signal. The millimeter-wavelength transceiver circuitry also includes mixers coupled to the local oscillator. The mixers are within an area without millimeter-wavelength structures. The mixers convert signals based on the millimeter-wavelength oscillator signal.
