SMA-isixhumi: incazelo, umsebenzi, kudivayisi ngezigaba

SMA-isixhumi yasungulwa ngo-1960 i-semi eqinile nakho ngeke kusize RG-402 ikhebula uhlobo (0.141 intshi). Lezi nezixhumi zenzelwe 50 Ohm impedance, futhi imvamisa 18 GHz (olulodwa ngokunemba izinguqulo bayakwazi sokuqhuba kuze kube 26,5 GHz). SMA-isixhumi has a kochungechunge uxhumano 1 / 4-36, ukuqina mechanical kanye nosayizi ezihlangene. Inani esiphezulu imvamisa yokusebenza ukuze nezixhumi ikhebula lincike ohlotsheni wire.

aphoyintimenti

High SMA-isixhumi has a ezihlukahlukene kakhulu ezingenzeka ezibhekwa izicelo, ipharamitha Ukhiye usayizi futhi imvamisa umngcele. I-radar ikhishiwe afanayo Instrumentation, amasistimu ithuluzi lokubikezela, namanye amadivayisi asebenzisa isigaba ofanayo, nezixhumi esinjalo lulwimi ngendlela elukhuni izintambo coaxial, futhi adapters ekhethekile (ipulaki nezixhumi) iyindlela elula eqondile isigaba isiqondiso.

SMA-isixhumi esakhiwe ngokuhambisana nezidingo standard, luhambisana nawo wonke izixhumi (kungakhathaliseki kwimodi) ahlangabezana lokhu sebhithi futhi ube ubukhulu efanayo. Zisetshenziswa kumadivayisi amaningi microwave: microstrip futhi coaxial-wave ukuhwebelana, attenuators, yokukhulisa umsindo, oscillators, ukushintshwa, labathaki bamafutha nokuhlunga.

izinhlobo nezixhumi

Zimbili izinhlobo SMA-isixhumi: SMA ( «isokhethi" futhi "ipulaki") futhi RP-SMA (futhi "isidleke" futhi "ipulaki").

Ngo omakhalekhukhwini (Wi-Fi iphuzu, ingabe i-WiMAX-kudivayisi adaptha) has a Isixhumi, okuyinto lebhokisi antenna (SMA isixhumi noma N-Uhlobo). Kusukela uxhumano ezifana inezingxenye ezimbili, ukuthi zonke nezixhumi nge indlela yochungechunge kukhona izinhlobo ezimbili, abhanqiwe komunye nomunye enethiwekhi futhi Imigudu. Okungukuthi, mithandazo screwed socket. Ukuze ubheke imigomo esetshenziswa isokhethi "Umama", "i-Jack" noma "owesifazane", izimfoloko - "Ubaba", "i-plug" noma "owesilisa."

Kukhona adapters ehlukahlukene adaptha izintambo phakathi kwezinhlobo ezihlukene izixhumi.

Eyesibili uhlobo isixhumi - lokhu isixhumi RP-SMA (nge polarity reverse noma okuhlanekezelwe). Ngo nezixhumi ezinjalo kuphambene: isixhumi has isokhethi oxhumana nabo kodwa izisekelo - Forklift. I ephambene reconfigured nezixhumi ngesikhathi pin emaphakathi.

ngezigaba nezixhumi

Ngendlela compounds nezixhumi Okubukwe zihlukaniswe amadivayisi nge elihlangana yochungechunge kanye insabule. Ngu indlela nezixhumi obandayo zimi Intulo, solder futhi crimp. On umklamo ithuluzi letihloniphekile, ikhebula, ogibele isiliphu wesifunda ibhodi ephezulu imvamisa nezixhumi futhi adapters.

amadivaysi Uphiko exhunywe izindlu esebenzisa flange isikwele noma nut. ukufakwa Ikhebula Kwenziwa nokunamathisela ngomthofu noma crimping. Nezixhumi igibele ibhodi ungenye nokunamathisela ngomthofu ebusweni nendawo noma ngenhla. Ikhebula nezixhumi awashintsheki nge crimping noma nokunamathisela ngomthofu. Adapters zisetshenziselwa ukuxhuma izinhlobo ezahlukene izixhumi.

isiphetho

I-computer hardware-SMA nezixhumi kabanzi nezinhlangano antenna Wi-Fi axhunyiwe. Zinikeza contact enokwethenjelwa kakhulu, kanye kunciphisa ukulahlekelwa okwenzeka emalungeni. izici eziyinhloko nezixhumi ezinjalo - ukuqina kanye ukumelana ukucindezeleka mechanical.
