New type of DBS receiver utilizing optical fiber as IF transmission line

An optical fiber transmission system that transmits the IF signal for direct broadcasting satellite (DBS) TV channels from a low noise converter to the main chassis of the DBS receiver after the IF signal at 1 GHz is converted into the corresponding second IF signal at 300 MHz (35-335 MHz) is described. The differential gain and differential phase of the video signal are less than 2% and 3 degrees, respectively, and the signal-to-noise ratio (SNR) is 45 dB.<
