Isixhumi esinamandla aphezulu we-SPNT RF switch
Uhlobo
● Iswishi yamandla aphezulu ye-SPNT ye-coaxial
● Imvamisa yokusebenza: DC-12.4GHz/18GHz
● Isixhumi se-RF: Uhlobo Lwesifazane lwe-N/SC
● Ozicabangelayo
Ukusebenza kwe-RF
Ukuhlukaniswa okuphezulu: okukhulu kuno-80 dB ku-6GHz, okukhulu kuno-70dB ku-12.4GHz;
I-VSWR ephansi: ngaphansi kuka-1.3 ku-6GHz, ngaphansi kuka-1.5 ku-12.4GHz;
I-Low Ins.less: ngaphansi kuka-0.3dB ku-6GHz, ngaphansi kuka-0.5dB ku-12.4GHz.
Ukuzinza kokuhlolwa kabusha kwe-RF nempilo ende yesevisi
Ukuzinza kokuphinda ukuhlolwa kokulahlekelwa kokufakwa: 0.02dB ku-6GHz, 0.03dB ku-12.4GHz;
Qinisekisa izikhathi eziyizigidi ezingu-2 zomjikelezo wempilo (Isiyingi sesiteshi esisodwa izikhathi eziyizigidi ezingu-2).
Umgomo wokusebenza we-RF switch
1. Iswishi yeleveli yokungena ye-RF isebenzisa itheminali emithathu ye-Cote – Shield ukuze kuqedwe umthelela wezinto ezinamathele ku-electrode etholwayo kumphumela wokulawula.Isignali yefrikhwensi ephezulu ekhiqizwa kusekethe ye-elekthronikhi ithunyelwa ngokuqondile ku-electrode etholwayo ngakolunye uhlangothi kanye nakumkhono ovikelayo ovikela ukunamathela ngomkhondo we-voltage ye-RF ngakolunye.Ubukhulu bayo kanye nesigaba kuyafana nesignali engezwe ku-probe rod.Lapho izinto ezisetshenziswayo zinamathela kuphenyo, i-capacitance yakheka phakathi komkhono wokuvikela nodonga lomgqomo, ngakho-ke isignali yefrikhwensi ephezulu engezwe kumkhono ovikelayo izogcwalisa amandla, ukuze isignali yefrikhwensi ephezulu ku-probe ingakwazi ukugeleza udonga lwesitsha ngokusebenzisa isendlalelo sokunamathela.Uma inani elikhulu lezinto eziku-container lithinta i-probe, i-current ku-probe izodlula indawo yokugcwala futhi igeleze odongeni lwesiqukathi, ngaleyo ndlela ikhiqize isignali yokuba khona kwezinto.
2. Iswishi yeleveli yokungena ye-RF isebenzisa ubuchwepheshe obunamaza aphezulu ukuze ikhiqize isignali ye-RF yamandla amancane ophenyweni olusuka kusekethe ye-elekthronikhi, futhi uphenyo lusebenza njengento ezwayo ukubuyisela emuva izinguquko zesignali ezibangelwa ukungaguquguquki kwe-dielectric kwezinga kuya i-electronic circuit;Ngenxa yokuthi lezi zinguquko zifaka phakathi izinguquko ze-capacitance kanye ne-conductance, isifunda se-elekthronikhi sicubungula ukusabela (isiginali yezinguquko eziphelele ze-capacitive reactance kanye ne-impedance) isignali.
3. Ukushintsha kokusabela kubangela ukuguqulwa kwesigaba sesignali ye-high-frequency esigxotsheni.Ngakho-ke, umehluko wesigaba phakathi kwesiginali yemvamisa ephezulu esigxotsheni kanye nesiginali yereferensi kusekethe kagesi nakho kuyashintsha.Ngemuva kokuthi ushintsho selucutshunguliwe, isekethe yokuphuma kwedrayivu ithumela isignali ye-alamu ukuthola ukuthi kukhona yini okubalulekile kusilo.
