Abstract:
1. An optical Low Noise Block down-converter (LNB) capable of fast position-adjusting utilized in a Low Noise Block Down-converter with Integrated Feed (LNBF) of a satellite communication receiving system, the optical LNB comprising: a down-converting device, coupled to an Orthomode Transducer (OMT) of the LNBF, for down-converting a polarized signal so as to generate a first Intermediate Frequency (IF) signal; a branching device, for branching the first IF signal, so as to generate a second and a third IF signals; an electrical/optical converting device, coupled to the branching device, for converting the second IF signal to an optical signal; and a power end for receiving power and outputting the third IF signal.
