Amaswishi e-RF ne-microwave angathumela amasignali ngendlela efanele endleleni yokudlulisela.Imisebenzi yalezi zinguquko ingabonakala ngamapharamitha kagesi amane ayisisekelo.Yize amapharamitha amaningana ehlobene nokusebenza kokushintshwa kwe-RF ne-microwave, lezi zinhlaka ezine ezilandelayo zithathwa njengezibalulekile ngenxa yokuhlobana kwazo okuqinile:
Ukuzihlukanisa
Ukuhlukaniswa wukuncishiswa phakathi kokufakwayo nokuphumayo kwesekethe.Kuyisilinganiso sokusebenza okunqanyuliwe kweswishi.
Ukulahlekelwa kokufaka
Ukulahlekelwa kokufaka (okubuye kubizwe ngokuthi ukulahlekelwa kokudluliswa) yisamba samandla alahlekayo lapho iswishi isesimweni.Ukulahlekelwa kokufaka kuyipharamitha ebaluleke kakhulu kubaklami ngoba kungaholela ngokuqondile ekwandeni kwesibalo somsindo wesistimu.
Ukushintsha isikhathi
Isikhathi sokushintsha sisho isikhathi esidingekayo ukuze usuke esimweni sokuthi "uvuliwe" uye esimweni "sokucisha" futhi usuke esimweni sokuthi "cima" uye kusimo "sokuvula".Lesi sikhathi singafinyelela kuma-microsecond wokushintshwa kwamandla aphezulu kanye nama-nanosecond wokushintshwa kwesivinini esiphezulu samandla aphansi.Incazelo evame kakhulu yokushintsha isikhathi isikhathi esidingekayo kusukela ku-voltage yokulawula okokufaka efinyelela ku-50% kuya emandleni okugcina e-RF okukhiphayo afinyelela ku-90%.
Amandla okucubungula amandla
Ukwengeza, umthamo wokubamba amandla uchazwa njengamandla amakhulu okufaka e-RF iswishi engamelana nawo ngaphandle kokuwohloka ugesi unomphela.
Iswishi ye-RF yesimo esiqinile
Amaswishi e-RF yesimo esiqinile angahlukaniswa ngohlobo olungabonisi kanye nohlobo lokubonisa.Iswishi engabonisi ifakwe isixhasi esifana netheminali esingu-50 ohm kumbobo ngayinye yokukhiphayo ukuze kuzuzwe isilinganiso esiphansi se-voltage stand wave ratio (VSWR) kuzo zombili izifunda zokuvula nezivaliwe.Itheminali yokumelana netheminali esethwe embobeni yokukhiphayo ingakwazi ukumunca amandla esignali yesigameko, kuyilapho imbobo engenakho ukumelana nokufanisa itheminali izobonisa isignali.Uma isignali yokokufaka kufanele isakazwe kuswishi, imbobo evulekile engenhla iyanqanyulwa kusimelaphi esifanayo setheminali, ngaleyo ndlela kuvumeleke amandla esiginali ukuthi asakazwe ngokuphelele kuswishi.Iswishi yokumuncwa ifanele izinhlelo zokusebenza lapho ukuboniswa kwe-echo komthombo we-RF kudinga ukuncishiswa.
Ngokuphambene, amaswishi akhanyayo awahlomekile ngezinqamuleli zetheminali ukuze kuncishiswe ukulahleka kokufakwa kwezimbobo ezivulekile.Amaswishi akhanyayo afanele izinhlelo zokusebenza ezingazweli isilinganiso segagasi sokuma samandla kagesi aphezulu ngaphandle kwembobo.Ngaphezu kwalokho, ekushintsheni okukhanyayo, ukufaniswa kwe-impedance kubonakala ngezinye izingxenye ngaphandle kwechweba.
Esinye isici esiphawulekayo sokushintshwa kwe-solid-state ama-circuits awo okushayela.Ezinye izinhlobo zokushintsha kwesimo esiqinile zihlanganiswe namashayeli kagesi wokulawula okokufaka.Isimo esinengqondo sokulawula okokufaka kwamandla kagesi kulawa mashayeli singafinyelela imisebenzi ethile yokulawula - sinikeze isimanje esidingekayo ukuze kuqinisekiswe ukuthi i-diode ingathola i-voltage echema ehlehlayo noma eya phambili.
Amaswishi e-RF ye-electromechanical kanye ne-solid-state RF angenziwa abe imikhiqizo ehlukahlukene enezici ezihlukahlukene zokupakisha nezinhlobo zezixhumi - imikhiqizo eminingi yokushintsha i-coaxial enamaza okusebenza afika ku-26GHz isebenzisa izixhumi ze-SMA;Kufika ku-40GHz, 2.92mm noma isixhumi sohlobo lwe-K sizosetshenziswa;Kufika ku-50GHz, sebenzisa isixhumi esingu-2.4mm;Kufika ku-65GHz sebenzisa izixhumi ezingu-1.85mm.
Sinohlobo olulodwa53GHz LOAD SP6T Coaxial Switch:

Siyakwamukela ukuthintana nethimba labadayisi ukuze uthole imininingwane!
