Zusammenfassung:A switching device for satellite signals is disclosed. The switching device includes a first switch circuit, a second switch circuit, and a controller. The first switch circuit is configured to receive 4 sets of legacy Low Noise Block converter (LNB) signals and select one of the 4 sets of LNB signals according to an analog control signal to output a first legacy output signal. The second switch circuit, including an output terminal, coupled to the first switch circuit, is configured to receive 2 sets of wideband LNB signals, receive a digital switching control signal to select one from the 2 sets of wideband LNB signals and the first legacy output signal to output a first switch output signal at the output terminal. The controller, coupled to the second switch circuit, is configured to generate the digital switching control signal according to a LNB Control signal.
