SMA-cholumikizira: kufotokoza, ntchito chipangizo gulu

SMA-cholumikizira anayamba kupanga mu 1960 chifukwa RG-402 chingwe mtundu theka-okhwima (0.141 inchi). zolumikizira awa anaikira 50 ohm impedance, ndi pafupipafupi 18 GHz (Mabaibulo umodzi mwatsatanetsatane amatha ntchito pa mpaka 26,5 GHz). SMA-cholumikizira ali kugwirizana yamazinga 1 / 4-36, makina durability ndi yaying'ono kukula. Mtengo pazipita pafupipafupi opaleshoni kuti zolumikizira chingwe zimatengera mtundu wa waya.

kusankhidwa

Mkulu SMA-cholumikizira ali osiyanasiyana kwambiri ofunsira, ndi chizindikiro kwambiri ndi kukula ndi pafupipafupi malire. The makina ounikira phased osiyanasiyana zipangizo, kachitidwe ankafika chida, ndi zipangizo zina kuti ntchito gawo ofananira, zolumikizira zimenezi kwa zingwe theka-okhwima coaxial, ndi adaputala azamagetsi wapadera (pulagi zolumikizira) ndi njira yosavuta yeniyeni gawo lamulo.

SMA-cholumikizira anamanga malinga ndi malamulo a muyezo, n'zogwirizana ndi zolumikizira onse (kaya wopanga) zomwe kukumana mfundo lino ndipo awiri chomwecho. Iwo ntchito zipangizo zambiri mayikirowevu: microstrip ndi coaxial-yoweyula kusintha, attenuators, amplifiers, oscillators, masiwichi, osanganiza ndi Zosefera.

mitundu ya zolumikizira

Pali mitundu iwiri ya SMA-cholumikizira: SMA ( «zitsulo" ndi "pulagi") ndi RP-SMA (komanso "chisa" ndi "pulagi").

Mu zipangizo opanda zingwe (Wi-Fi kupeza mfundo, WiMAX-chipangizo adaputala) ali cholumikizira, zomwe zikugwirizana ndi mlongoti (SMA cholumikizira kapena N-Type). Popeza mogwirizana ngati idzafotokoza awiri, kuti zolumikizira onse ndi limagwirira yamazinga mitundu iwiri, wophatikizidwa ndi zokhazikapo mzake ndi mapulagi. Ndiko kuti, yamasika tili m'mavuto mu bowo la. Kunena kuti mawu ntchito ndi zitsulo "mayi", "Jack" kapena "mkazi", ndi mafoloko - "Bambo", "pulagi" kapena "mwamuna".

Pali adaputala azamagetsi zosiyanasiyana ndi zingwe adaputala pakati pa mitundu yosiyanasiyana ya zolumikizira.

Mtundu wachiwiri wa cholumikizira - cholumikizira ichi RP-SMA (ndi polarity n'zosiyana kapena Imatithandiza). Mu zolumikizira amenewa ndi zosiyana: cholumikizira ali zitsulo kukhudzana, koma zitsulo - forklift. The osiyanitsidwa reconfigured zolumikizira pa pini chapakati.

zolumikizira gulu

Mwa njira ya mankhwala zolumikizira ankaona anawagawa zipangizo ndi lumikiza yamazinga ndi mpeni. Mwa njira ogwiritsa zolumikizira ndi kagwere, solder ndipo crimp. Pa chida kapangidwe wolemekezeka, chingwe, wokwera pa kusindikizidwa dera bolodi zolumikizira mkulu-pafupipafupi ndi adaputala azamagetsi.

Chigawo zipangizo Ufumuyo nyumba ya mwa flange lalikulu kapena mtedza. Chingwe unsembe ikuchitika ndi soldering kapena crimping. Zolumikizira wokwera pa bolodi Ufumuyo ndi soldering pamwamba horizontally kapena vertically. Chingwe zolumikizira ndi kuliika ndi crimping kapena soldering. Adaputala azamagetsi ntchito kulumikiza osiyanasiyana zolumikizira.

Pomaliza

The kompyuta hardware-SMA zolumikizira ankagwiritsa ntchito mabungwe tinyanga zipangizo Wi-Fi. Iwo amapereka kukhudzana odalirika, komanso minimizes ndi zomvetsa kunachitika malo. Main makhalidwe a zolumikizira ngati - durability ndi kukana nkhawa makina.
