1. An apparatus for wireless transmission of high data rate optical signals comprising:

  • an electrical converter for converting a received optical signal containing a high data rate digital signal to a received electrical signal;

    a clock and data recovery circuit for recovering the high data rate signal from the received electrical signal;

    an encoder for encoding the high data rate signal as an encoded electrical signal;

    a symbol modulator for modulating the encoded electrical signal to produce a Quadrature Amplitude Modulated (QAM) signal at an intermediate frequency (IF); and

    a microwave up converter for converting the QAM-IF signal to a single carrier microwave radio frequency carrier signal, andwherein the microwave up converter converts the QAM-IF signal to a millimeter wave signal at 20 Gigahertz or higher.
