Abstract
A remote antenna unit includes an uplink integrated circuit (IC) and a downlink IC. The uplink IC includes an uplink synthesizer that provides an uplink oscillating signal; an uplink mixer stage that mixes an uplink radio frequency signal with the uplink oscillating signal to produce an uplink intermediate frequency signal; and an uplink control interface that receives uplink commands that control the frequency of the uplink oscillating signal. The downlink IC includes a downlink synthesizer that provides a downlink oscillating signal; a downlink mixer stage that mixes the downlink intermediate frequency signal with a downlink oscillating signal to produce a down link radio frequency signal; a downlink control interface that receives downlink commands that control the frequency of the downlink oscillating signal. The antenna unit also includes a clock that provides a reference frequency to the uplink and downlink synthesizers.
