Abstract
A high frequency signal is down-converted into an intermediate frequency signal, transmitted over a limited bandwidth medium from a master unit to a remote unit and up-converted back into its original high frequency at the remote unit. The up-conversion is aided by reconstruction of a reference signal embedded at the master unit as a carrier for a management signal which is transmitted to the remote unit through the same limited bandwidth medium together with the intermediate frequency signal. The reference signal is reconstructed using a phase locked loop which includes a charge pump and is kept stable during intervals between bits and messages by a charge pump shutter.
