Ukuqonda ama-Phaphamathi: Izinkomba zomsebenzi obalulekile ekwakhiweni kwe-RF

Isingeniso se-S-Pharameters: Ukubuka konke okufushane

Emikhakheni ye-Wireless kanye ne-Radio Frequency Bachaza izici zokusakazwa kwezimpawu ze-RF kumadivayisi ahlukene namanethiwekhi, ikakhulukazi kumanethiwekhi amaningi ethekwini afana nama-amplifiers, izihlungi, noma abalandeli. Onjiniyela abangewona ama-RF, ukuqonda la mapharamitha kungakusiza uqonde kangcono ubunzima be-RF design.

Yini amapharamitha we-S?

Ama-S-parameter (amapharamitha wokusakaza) asetshenziselwa ukuchaza ukuboniswa kanye nezimpawu zokuhambisa zezimpawu ze-RF kumanethiwekhi etheku amaningi. Ngamagama alula, anciphisa ukusakazwa kwamasiginali ngokulinganisa isigameko futhi akhombisa amagagasi esibonakaliso emachwebeni ahlukahlukene. Ngalezi zinhlaka, onjiniyela bangakuqonda ukusebenza kwensiza, njengokulahleka kokubonisa, ukulahleka kokuhambisa, njll. Isiginali.

Izinhlobo eziphambili ze-S-parameters

Amapharamitha amancane we-S-Namapharali: Chaza impendulo yedivayisi ngaphansi kokuthokozisa okuncane kwesiginali futhi asetshenziselwa ukunquma izici ezinjengokulahlekelwa kokubuyiselwa kwemali nokulahleka kokufaka.

Amapharamitha amakhulu ama-s-siginali: esetshenziselwa ukukala imiphumela engeyona eyengaphandle lapho amandla wesiginali emukhulu, isiza ukuqonda ukuziphatha kwensiza okungeyona.

I-Pulsed S-Pharameters: Nikeza idatha enembile ukwedlula amapharamitha wendabuko wamadivayisi wesiginali e-Pulsed.
Amapharamitha ama-Cold Mode: Chaza ukusebenza kwensiza esesimweni esingasebenzi futhi asize ukwengeza izici ezifanayo.
Amapharamitha wemodi ehlanganisiwe: esetshenziselwa amadivaysi ahlukile, asiza ukuchaza izimpendulo zemodi ehlukile nejwayelekile.

Ukubeka kafushane

Amapharamitha e-S liyithuluzi elibalulekile lokuqonda nokwandisa ukusebenza kwezakhi ze-RF. Noma ngabe kusiginali esincane, isiginali ye-pulse, noma izinhlelo ezinkulu zesiginali, amapharamitha amaningi ahlinzeka ngonjiniyela ngedatha ebalulekile ekusebenzeni kwensiza. Ukuqonda la mapharamitha akuwona kuphela okusiza ukwakheka kwe-RF, kepha futhi kusiza onjiniyela abangawona ama-RF baqonde kangcono ubulukhuni bezobuchwepheshe be-RF.
