Nigute ushobora guhitamo RF Coaxial switch?

Guhindura coaxial ni pasiporo ya elegitoroniki ikoreshwa muguhindura ibimenyetso bya RF kuva kumuyoboro ujya mubindi.Ubu bwoko bwa switch bukoreshwa cyane mubihe byerekana ibimenyetso bisaba inshuro nyinshi, imbaraga nyinshi, hamwe nibikorwa bya RF.Irakoreshwa kandi muri sisitemu yo kwipimisha RF, nka antene, itumanaho rya satelite, itumanaho, sitasiyo fatizo, indege, cyangwa izindi porogaramu zisaba guhinduranya ibimenyetso bya RF kuva kuruhande rumwe.

Hindura icyambu
NPMT: bisobanura n-pole m-guta, aho n numubare winjira ibyambu na m numubare wibisohoka.Kurugero, RF ihinduranya icyambu kimwe cyinjiza hamwe nibisohoka bibiri byitwa pole imwe inshuro ebyiri, cyangwa SPDT / 1P2T.Niba RF ihindura ifite ibyinjijwe hamwe nibisohoka 6, noneho dukeneye guhitamo SP6T RF.

Ibiranga RF
Mubisanzwe dufata ibintu bine: Shyiramo igihombo, VSWR, Kwigunga n'imbaraga.

Ubwoko bwinshyi:
Turashobora guhitamo coaxial switch ukurikije intera ya sisitemu yacu.Umubare munini dushobora gutanga ni 67GHz.Mubisanzwe, turashobora kumenya inshuro ya coaxial switch ishingiye kubwoko bwayo.
Umuhuza wa SMA: DC-18GHz / DC-26.5GHz
N Umuhuza: DC-12GHz
2.92mm Umuhuza: DC-40GHz / DC-43.5GHz
1.85mm Umuhuza: DC-50GHz / DC-53GHz / DC-67GHz
Umuhuza wa SC: DC-6GHz

Impuzandengo y'imbaraga: Munsi yishusho yerekana impuzandengo ya power db igishushanyo mbonera.

Umuvuduko:
Ihinduka rya coaxial ririmo amashanyarazi ya magnetiki na magnet, bisaba ingufu za DC kugirango uhindure inzira ijyanye na RF.Ubwoko bwa voltage bukunze gukoreshwa muri swaxial coaxial nuburyo bukurikira: 5V.12V.24V.28V.Mubisanzwe abakiriya ntibazakoresha 5V voltage itaziguye.Dushyigikiye amahitamo TTL kugirango tureke voltage nkeya nka 5v kugenzura RF ihinduka.

Ubwoko bw'imodoka ：
Failsafe ： Iyo nta voltage yo kugenzura ikoreshwa, umuyoboro umwe uhora ukora.Ongeraho amashanyarazi yo hanze, umuyoboro wa RF ukorwa kurindi.Iyo voltage yahagaritswe, umuyoboro wa RF wahoze ukora.
Gufunga: Guhindura ubwoko bwa switch ikenera guhora itanga amashanyarazi kugirango umuyoboro wa RF ugaragare neza.Amashanyarazi amaze kubura, disiki yamashanyarazi irashobora kuguma mumwanya wanyuma.
Mubisanzwe Gufungura: Ubu buryo bwo gukora bufite agaciro kuri SPNT gusa.Hatabayeho kugenzura voltage, imiyoboro yose yo guhindura ntabwo ikora;Ongeramo amashanyarazi yo hanze hanyuma uhitemo umuyoboro wateganijwe kugirango uhindure;Iyo voltage yo hanze idashyizwe mubikorwa, switch isubira muri reta aho imiyoboro yose idakora.

Icyerekana: Iyi mikorere ifasha kwerekana ihinduka ryimiterere.
