Abstract
A satellite communications system has a hub terminal which communicates with a remote terminal through a satellite. The hub terminal 100 includes a transmitting modulator, power booster, up-converter and Power Amplifier (PA), and a transmitting station. The transmitting modulator generates a modulated signal, which is output to the power booster. The power booster receives the modulated signal and generates a spectral replication of the signal. The signal is then up-converted and amplified, and transmitted as an uplink signal to the satellite via a transmitting antenna. A remote station antenna receives the corresponding downlink signal. Following LNB/LNA and down-conversion, the signal is passed to a diversity combiner. The diversity combiner aligns the replicated signals by frequency and phase and generates a power-boosted signal. Accordingly, the system enables the use of ultra small antennas by providing increased power.
