Abstract:
1. A system for adjusting a composite signal transmitted from a VSAT transmitter to a VSAT receiver, wherein the composite signal includes at least a DC power signal, a clock signal, and a modulated-information signal, the system comprising: a first set of filters comprising: a first amplifier to amplify the clock signal; a gain control stage wherein the amplified clock signal is passed through the gain control stage; a second amplifier to amplify the modulated-information signal; an equalizer to equalize the amplified modulated-information signal; a fourth filter to prevent the clock signal from being amplified by the second amplifier; a fifth filter to prevent the clock signal from being amplified by the first amplifier; and a signal combiner which receives the modulated-information signal from the fourth filter, the clock signal from the fifth filter, and the DC power signal and outputs a composite signal of the modulated-information signal from the fourth filter, the clock signal from the fifth filter, and the DC power signal.
