Systems and methods for implementing a distributed antenna system in a radio frequency integrated circuit

A distributed antenna system, the system comprising:

• at least one hub unit configured to communicate with a base station;
• a plurality of remote antenna units communicatively coupled to the at least one hub and configured to communicatively couple signals between the at least one hub and a plurality of wireless terminals, a remote antenna unit in the plurality of remote antenna units comprising:
• an uplink integrated circuit, wherein the uplink integrated circuit receives a radio frequency signal, the uplink integrated circuit comprising:
• an uplink synthesizer configured to provide an uplink oscillating signal in at least one frequency;
• an uplink mixer stage coupled to the uplink synthesizer, the uplink mixer stage configured to mix the radio frequency signal with the uplink oscillating signal to produce an uplink intermediate frequency signal;
• and
• an uplink control interface configured to receive uplink commands that control the frequency of the uplink oscillating signal;
• the remote antenna unit also comprising a downlink integrated circuit that is electrically isolated from the uplink integrated circuit, wherein the downlink integrated circuit receives a downlink intermediate frequency signal, the downlink integrated circuit comprising:
• a downlink synthesizer configured to provide a downlink oscillating signal in at least one frequency;
• a downlink mixer stage coupled to the downlink synthesizer, the downlink mixer stage configured to mix the downlink intermediate frequency signal with the downlink oscillating signal to produce a down link radio frequency signal;
• a downlink control interface configured to receive downlink commands that control the frequency of the downlink oscillating signal.
