SMA-xira: description, shaqada, kala soocidda qalabka

SMA-xira waxaa la sameeyey 1960 for semi-adag RG-402 cable nooca (0.141 inch). Xidhiidhiyayaasha Kuwan waxaa loogu talagalay 50 impedance Ohm, iyo inta jeer ee 18 GHz (versions sax hal ay awoodaan in ay shaqeeyaan ilaa 26.5 GHz). SMA-xira ayaa xiriir xidhnayn 1 / 4-36, cimri dherer si farsamaysan iyo size is haysta. Qiimaha ugu badan ee inta jeer u hawlgasho Xidhiidhiyayaasha cable ee waxay ku xiran tahay nooca silig.

ballan

High SMA-xira kala duwan oo aad u balaadhan oo ah codsiyada, Halbeegga ugu muhiimsan waa size iyo inta jeer soohdinta. radar joojinayaa instrumentation la dagaallamaan, nidaamyada degtey qalab, iyo qalabka kale ee isticmaala dhigma wajiga, Xidhiidhiyayaasha sida for fiilooyinka coaxial semi-adag, iyo adapters gaar ah (Xidhiidhiyayaasha fur) waa hab saxda fudud of regulation wajiga.

SMA-xira dhisay iyada oo la raacayo shuruudaha heerka, waa la jaan qaada oo dhan Xidhiidhiyayaasha (eegin saaraha) oo soo baxaysid faahfaahinta this oo ay leeyihiin ballaciisu yahay isku. Waxay waxaa loo isticmaalaa in hindisooyin badan microwave: microstrip iyo coaxial-ruxruxo guurka, attenuators, Sammeecado, oscillators, daaro, ooyinka iyo filtarrada.

nooc oo Xidhiidhiyayaasha

Waxaa jira laba nooc oo SMA-xira: SMA ( «dalool" iyo "fur") iyo RP-SMA (oo sidoo kale "buul" iyo "fur").

In qalabka wireless (Wi-Fi helaan dhibic, WiMAX-qalab adabtarada) ayaa isku xira a, kaas oo isku xira antenna ah (isku xira SMA ama N-Type). Tan iyo markii la xidhiidha sida uu ka kooban yahay laba qaybood, in dhammaan Xidhiidhiyayaasha la farsamo xidhnayn jira laba nooc, aaday in kasta oo saldhig kale oo gelanayo. Taasi waa, ugu dambaysta la xiri galay godka. Si tixraac shuruudaha loo isticmaalo by godka "hooyo" ka, "Jack" ama "dumar", iyo mudacyadii - "Aabaha", "fur" ama "lab".

Waxaa jira adapters kala duwan iyo fiilooyinka adabtarada u dhexeeya noocyada kala duwan ee Xidhiidhiyayaasha.

Nooca labaad ee isku xira - xira this RP-SMA (la polarity dambe ama rogay). In Xidhiidhiyayaasha sida yahay mid kasoo horjeeda: xira leeyahay xiriir godka, laakiin godka - forklift. -bedelka beddeshay Xidhiidhiyayaasha at pin dhexe.

Xidhiidhiyayaasha soocidda

By habka xeryahooda Xidhiidhiyayaasha viewed kala qaybsan yihiin qalabka la xigay xidhnayn iyo soor. By habka of Xidhiidhiyayaasha sii kordhaya waa marooji, Alxan iyo crimp. On qalab design distinguished, cable, dhajinta on a guddiga circuit daabacay Xidhiidhiyayaasha ee hirka sare iyo adapters.

qalabka Qeybta lifaaqan guryaha taasi oo ka flange a square ama lowska. rakibaadda Cable waxaa lagu fuliyaa by kabida crimping. Xidhiidhiyayaasha dhajinta on board a lifaaqan by kabida dusha gudban ama vertical. Xidhiidhiyayaasha Cable go'an yihiin la crimping ama kabida. Adapters waxaa loo isticmaalaa in lagu xiro noocyada kala duwan ee Xidhiidhiyayaasha.

gunaanad

The Xidhiidhiyayaasha computer hardware-SMA hubkaas ayaa loo isticmaalaa in ururada anteenooyinkooda qalabka Wi-Fi. Waxay bixiyaan xiriir lagu kalsoonaan karo, iyo sidoo kale yaraynaysaa khasaaraha ka dhaca ku jira laabatooyinka ee. astaamaha ugu muhiimsan ee Xidhiidhiyayaasha sida - cimri dherer iyo caabiga stress makaanikada.
