Ukuxhumana ngesathelayithi

I-Low Noise Amplifier (LNA) kanye nesihlungi zingathuthukisa ukusebenza kwesistimu nekhono lokulwa nokuphazamiseka ngokuthuthukiswa kwesignali nokunciphisa umsindo, ukuhlunga isignali nokubunjwa kwe-spectrum kwezokuxhumana ngesathelayithi.

1. Ekupheleni kokwamukela kokuxhumana ngesathelayithi, i-LNA isetshenziselwa kakhulu ukukhulisa amasignali abuthakathaka.Ngesikhathi esifanayo, ama-LNA nawo adinga ukuba nezici zomsindo ophansi ukuze agweme ukukhulisa umsindo ndawonye, okungase kuthinte isilinganiso sesignali-kuya-nomsindo sayo yonke isistimu.

2. Izihlungi zingasetshenziswa kwezokuxhumana ngesathelayithi ukucindezela amasignali aphazamisayo bese ukhetha ibhendi yefrikhwensi yesiginali oyifunayo.

3. Isihlungi se-band-pass singasefa isignali kubhendi yefrikhwensi eshiwo futhi siyisebenzisele ukukhetha ibhendi yefrikhwensi oyifunayo yokuxhumana kwesiteshi.
