Ukuqonda i-S-Parameters: Izalathisi eziphambili zokuSebenza kwi-RF Design

Intshayelelo kwi-S-Parameters: Umboniso omfutshane

Kuyilo lonxibelelwano olungenazingcingo kunye nerediyo yerediyo (RF), iiparamitha zokusasaza (ii-S-parameters) sisixhobo esibalulekileyo esisetyenziselwa ukulinganisa ukusebenza kwamacandelo e-RF. Bachaza iimpawu zokusasaza kweempawu zeRF kwizixhobo ezahlukeneyo kunye nothungelwano, ngakumbi kuthungelwano lwezibuko ezininzi ezifana neamplifiers, izihluzi, okanye izithinteli. Kwiinjineli ezingezizo ezeRF, ukuqonda ezi parameters kunokukunceda uqonde ngcono ukuntsonkotha koyilo lweRF.

Yintoni i-S-parameters?

I-S-parameters (iiparamitha zokusasaza) zisetyenziselwa ukuchaza ukubonakaliswa kunye neempawu zokuhambisa iimpawu ze-RF kwiinethiwekhi ezininzi. Ngamagama alula, balinganisa ukusasazwa kweempawu ngokulinganisa isiganeko kwaye babonakalise amaza omqondiso kumachweba ahlukeneyo. Ngale parameters, iinjineli zinokuqonda ukusebenza kwesixhobo, njengokulahleka kokubonakalisa, ukulahleka kokuhanjiswa, njl njl.

Iindidi eziphambili ze-S-Parameters

Iimpawu ezincinci ze-S-parameters: Chaza impendulo yesixhobo phantsi kwe-excitation encinci yesignali kwaye isetyenziselwa ukumisela iimpawu ezifana nokulahlekelwa kokubuyisela kunye nokulahlekelwa kokufaka.

Iimpawu ezinkulu ze-S-parameters: Isetyenziselwa ukulinganisa imiphumo engabonakaliyo xa umbane wesignali mkhulu, unceda ukuqonda ukuziphatha okungahambiyo kwesixhobo.

I-Pulsed S-parameters: Ukubonelela ngedatha echaneke ngakumbi kune-S-parameters yesiqhelo yezixhobo ze-pulsed signal.
Iiparamitha zendlela ebandayo ye-S: chaza ukusebenza kwesixhobo kwimeko engasebenziyo kwaye uncede ukuphucula iimpawu ezihambelanayo.
I-Mixed mode S parameters: isetyenziselwa izixhobo ezihlukeneyo, nceda ukuchaza ukwahlukana kunye neempendulo zemowudi eziqhelekileyo.

Isishwankathelo

Iiparamitha ze-S zisisixhobo esibalulekileyo sokuqonda kunye nokwandisa ukusebenza kwezixhobo zeRF. Nokuba kuphawu oluncinci, umqondiso wepulse, okanye usetyenziso lwesignali enkulu, iiparamitha ze-S zibonelela iinjineli ngedatha engundoqo ukulinganisa ukusebenza kwesixhobo. Ukuqonda ezi parameters akuncedi kuphela uyilo lweRF, kodwa kukwanceda iinjineli ezingezizo ezeRF ziqonde ngcono ukuntsonkotha kobuchwepheshe beRF.
