Ukuqonda Amapharamitha we-S: Izinkomba Zokusebenza Ezibalulekile Kumklamo We-RF

Isingeniso se-S-Parameters: Uhlolojikelele Olufushane

Ekwakhiweni kwezokuxhumana okungenantambo kanye nefrikhwensi yomsakazo (RF), amapharamitha wokusakaza (amapharamitha we-S) ayithuluzi elibalulekile elisetshenziselwa ukulinganisa ukusebenza kwezingxenye ze-RF. Bachaza izici zokusabalalisa zamasiginali e-RF kumadivayisi ahlukene namanethiwekhi, ikakhulukazi kumanethiwekhi anezimbobo eziningi njengezikhulisi, izihlungi, noma izibambisi. Konjiniyela abangewona ama-RF, ukuqonda le mingcele kungakusiza uqonde kangcono ubunkimbinkimbi bomklamo we-RF.

Ayini amapharamitha we-S?

Amapharamitha we-S (amapharamitha ahlakazayo) asetshenziselwa ukuchaza izici zokubonisa nokudluliswa kwamasignali e-RF kumanethiwekhi anezimbobo eziningi. Ngamagama alula, balinganisa ukusakazwa kwezimpawu ngokulinganisa isigameko futhi babonise amagagasi esignali kumachweba ahlukene. Ngala mapharamitha, onjiniyela bangaqonda ukusebenza kwedivayisi, njengokulahlekelwa kokuboniswa, ukulahleka kokudlulisela, njll. kwesiginali.

Izinhlobo Eziyinhloko zama-S-Parameters

Amapharamitha wesignali encane ye-S: Chaza impendulo yedivayisi ngaphansi kwesasasa lesignali encane futhi asetshenziselwa ukunquma izici ezifana nokulahlekelwa kokubuyisela kanye nokulahlekelwa kokufaka.

Amapharamitha we-S-signal enkulu: Asetshenziselwa ukulinganisa imiphumela engaqondile uma amandla esignali emakhulu, okusiza ukuqonda ukuziphatha okungaqondile kwedivayisi.

Amapharamitha e-Pulsed S: Nikeza ngedatha enembe kakhulu kunamapharamitha we-S endabuko wamadivayisi esignali ashayekile.
Amapharamitha wemodi ebandayo S: chaza ukusebenza kwedivayisi esimweni sokungasebenzi futhi usize ukuthuthukisa izici ezifanayo.
Amapharamitha wemodi ehlanganisiwe S: asetshenziselwa izinto ezihlukile, asiza ukuchaza izimpendulo zemodi ehlukile nezijwayelekile.

Isifinyezo

Amapharamitha e-S ayithuluzi elibalulekile lokuqonda nokwenza kahle ukusebenza kwezingxenye ze-RF. Kungakhathaliseki ukuthi kusignali encane, isignali ye-pulse, noma izinhlelo zokusebenza zesignali ezinkulu, amapharamitha we-S ahlinzeka onjiniyela ngedatha ebalulekile ukuze kulinganise ukusebenza kwedivayisi. Ukuqonda le mingcele akusizi nje kuphela ukuklama kwe-RF, kodwa futhi kusiza onjiniyela abangewona ama-RF baqonde kangcono ubunkimbinkimbi bobuchwepheshe be-RF.
