SWITCHING DEVICE FOR SATELLITE SIGNALS

摘要

A switching device for satellite signals is disclosed. The switching device includes first and second switching circuits and a controller. The first switching circuit is configured to receive four sets of legacy Low Noise Block converter (LNB) signals and select one of the four sets of LNB signals according to an analog control signal to output a first legacy output signal. The second switching circuit is coupled to the first switching circuit, and includes an output terminal. The second switching circuit receives two sets of wideband LNB signals, and receives a digital switching control signal to select one of the two sets of wideband LNB signals and the first legacy output signal to output a first switching output signal at the output terminal. The controller, coupled to the second switching circuit, is configured to generate the digital switching control signal according to an LNB control signal.
