Ukuxhumana ngesathelayithi

I-Low Noise Amplifier (LNA) kanye ne-Filter kungathuthukisa ukusebenza kwesistimu kanye nekhono lokulwa nokuphazamiseka ngokuthuthukisa isignali kanye nokunciphisa umsindo, ukuhlunga isignali kanye nokwakheka kwe-spectrum ekuxhumaneni kwesathelayithi.

1. Engxenyeni yokwamukela ukuxhumana kwesathelayithi, i-LNA isetshenziswa kakhulu ukukhulisa izimpawu ezibuthakathaka. Ngesikhathi esifanayo, ama-LNA nawo kudingeka abe nezici zomsindo ophansi ukuze agweme ukukhulisa umsindo ndawonye, okungathinta isilinganiso sesiginali nomsindo sohlelo lonke.

2. Izihlungi zingasetshenziswa ekuxhumaneni kwesathelayithi ukucindezela izimpawu eziphazamisayo nokukhetha ibhendi yemvamisa yesignali oyifunayo.

3. Isihlungi se-band-pass singahlunga isignali ebhendini yemvamisa ecacisiwe bese siyisebenzisa ukukhetha ibhendi yemvamisa oyifunayo yokuxhumana kwesiteshi.
