Abstract
An optical LNB capable of fast position-adjusting is employed in an LNBF. The optical LNB includes a down-converting device coupled to an OMT of the LNBF for down-converting a polarized signal for generating a first intermediate frequency signal, a branching device for branching the first intermediate frequency signal for generating a second and a third intermediate frequency signals, an electrical/optical converting device coupled to the branching device for converting the second intermediate frequency signal into an optical signal, and a power end for receiving power from a power supply and outputting the third intermediate frequency signal.
Claims7
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.
