Title: Architecture for wireless transmission of high rate optical signals

Abstract: An apparatus for a wireless transmission of high data rate signals such as received from an optical interface including gigabit fiber channel or a sonet. The architecture combines direct detection of the optical signal with clock and data recovery circuit and a differential signal encoder which is preferably a differential quadrature phase shift encoder and modulator pair. A millimeter wave, local oscillator and up conversion chain converts the optical input signal to a microwave carrier. In the opposite direction, the down converted signal is non-coherently phase detected and fed to a pair of synchronized clock and data recovery circuits to recover I and Q channel signals. These recovered signals are then combined prior to re-timing before they are fed back to the optical transceiver.
