Malo olumikizirana ma satellite

Kugwiritsa ntchito kwakukulu kwa tinyanga ndi ma amplifiers m'malo olumikizirana ma satellite ndi motere:

1. Mlongoti: Zizindikiro zoyankhulirana za satellite ziyenera kutumizidwa kuchokera ku mlongoti wapansi kupita ku setilaiti komanso kuchokera ku setilaiti kubwerera pansi. Chifukwa chake, mlongoti ndi gawo lofunikira pakutumiza chizindikiro, chomwe chimatha kuyang'ana chizindikirocho panthawi imodzi ndikuwongolera mphamvu ndi mtundu wa chizindikirocho.

2. Amplifier: Chizindikirocho chimachepetsedwa panthawi yotumizira, kotero amplifier amafunikira kuti awonjezere mphamvu ya chizindikiro ndikuonetsetsa kuti chizindikirocho chikhoza kufika pa satana ndi olandila pansi. Ma amplifier omwe amagwiritsidwa ntchito m'malo olumikizirana ma satellite nthawi zambiri amakhala amplifier yaphokoso (LNA), yomwe imakhala ndi phokoso lochepa komanso kupindula kwakukulu, komwe kumatha kupititsa patsogolo kukhudzidwa kwa siginecha yolandilidwa. Nthawi yomweyo, amplifier itha kugwiritsidwanso ntchito kumapeto kwa transmitter kukulitsa chizindikiro kuti chikwaniritse mtunda wautali wotumizira. Kuphatikiza pa tinyanga ndi ma amplifiers, malo olumikizirana ma satellite amafunikira zinthu zina, monga zingwe za RF ndi masiwichi a RF, kuti zitsimikizire kutumiza ndi kuwongolera kosalala.
