US Patent 10090883 Radio frequency interconnect having a preamble generator

A radio frequency interconnect includes a transmitter coupled with an input end of a transmission line, and a receiver coupled with an output end of the transmission line. The transmitter includes a first carrier generator configured to generate a clock recovery signal based on a carrier signal, to output a reference clock signal, and to transmit the clock recovery signal to the receiver. The transmitter also includes a modulator configured to modulate a data packet based on the carrier signal. The transmitter also includes a preamble generator configured to generate and add a preamble to data to generate the data packet. The preamble includes a data sequence associated with the reference clock signal. The transmitter further includes a transmitter output configured to transmit the modulated data packet to the receiver by the transmission line.
