1. A central unit for providing communications signals in a distributed antenna system, comprising:

  • a radio-frequency (RF) communications interface configured to;

    receive downlink RF communication signals at a RF communications frequency for a RF communications service; and

    provide uplink RF communication signals at the RF communications frequency for the RF communications service;

    at least one RF integrated circuit (IC) (RFIC) chip comprising at least one of;

    a first frequency conversion circuitry configured to shift a frequency of the downlink RF communication signals to an intermediate frequency (IF) having a different frequency than the RF communications frequency, to provide downlink IF communications signals; and

    a second frequency conversion circuitry configured to shift the frequency of uplink IF communication signals to the RF communications frequency to provide the uplink RF communications signals; and

    a communications interface comprising RF communications circuitry configured to;

    provide the downlink IF communications signals over a communications medium to one or more remote units (RUs); and

    receive the uplink IF communication signals provided over a communications medium from the one or more RUs and provide the uplink IF communication signals to the second frequency conversion circuitry.
