Feeder SMA ihuza ntabwo arikindi kintu kigizwe na RF-ni amafarashi adakoreshwa muri sisitemu yo gukwirakwiza ibimenyetso aho kwizerwa bidashobora kumvikana. Twabonye bananiwe munsi yumukino wo gusiganwa ku magare muri sitasiyo yo hanze. Twabonye ko bafashe-nta drift cyangwa igihombo-nyuma yincuro 5000 zo gushakana muri laboratoire zigendanwa. Kandi twumvise abajenjeri bavuga, * “Niba ibiryo SMA igumye ihamye, umurongo wose uguma uteganijwe.” * Ibyo ntabwo ari ibiganiro byo kwamamaza. Nukuri kugenzurwa nukuri.

Niki Cyakora Kugaburira SMA Kurenza Umuhuza gusa?

Igaburira SMA ntabwo isobanurwa nu murongo wacyo wonyine. Imikorere yacyo ishingiye kubintu bitatu bihinduka-byukuri: guhuza impedance kumirongo yumurongo (mubisanzwe 50 Ω ± 0.3 Ω kuva DC kugeza 18 GHz), gusubiramo imashini munsi yinyeganyeza, hamwe nigihe kirekire cyo kurwanya okiside na galling. Kunanirwa kwinshi twasuzumye ntabwo byatewe nigishushanyo mbonera - ariko guhuza insinga zidahuye, gukoresha torque idahuye, cyangwa gukoresha amaboko ya dielectric adafite amanota ahantu hafite ubushyuhe bwinshi.

Ihuza ryukuri-SMA ihuza ikoresha umubiri wumuringa usize ifeza hamwe na PTFE cyangwa insimburangingo ya PTFE-ntabwo ari polyethylene rusange. Hagati ya pin igomba gukomeza <0,02 mm yiruka nyuma yo guhuza inshuro nyinshi. Igihombo cyo gushiramo kiguma munsi ya 0.15 dB kuri 6 GHz mugihe ushyizweho neza. Igihombo cyo kugaruka kirenze 30 dB kugeza 12 GHz. Iyi mibare ifite akamaro kuko igira ingaruka ku buryo butaziguye igipimo cya 5G ihuza imbere hamwe nicyiciro gihamye mugice cya radar igaburira.

Turagerageza buri cyiciro turwanya MIL-STD-348B kugirango imikorere ya RF na IEC 61169-10 yo kwihanganira imashini. Nta bigufi. Nta “byiza bihagije.” Kuberako mugukwirakwiza antenne ya sisitemu cyangwa EMC igerageza, imwe ihuza marginal ihuza sisitemu-urwego rutajegajega.

Kuki SMA isanzwe idahagije-Kandi Niki Gushakisha Ahubwo

Bamwe bashobora kuvuga ko SMA iyo ari yo yose yanditseho "urwego rwa RF" izakora. Nubwo bimeze bityo ariko, ubucuruzi busanzwe bwa SMA bukunze gusimbuka kugenzura inzitizi zagenzuwe muri zone yinzibacyuho, gukoresha uburebure bwa plaque budahuye, no kubura ibyemezo bifatika. Mubimenyerezo, bivuze ko hejuru ya VSWR hejuru ya 8 GHz, guhura rimwe na rimwe mugihe cyo kwagura ubushyuhe, no kwambara imburagihe nyuma yizuba 1200 - ntabwo 5.000+ byateganijwe mubagaburira ubutumwa.

Itandukaniro ryerekanwa ahantu hatatu:

Twasimbuye ibiryo birenga 200 byananiranye kugaburira muri retrofits yumunara wa terefone - kandi burigihe, intandaro yaturutse kumurongo udahuza uhuza-na kabili ya geometrie, ntabwo antenne cyangwa amplifier.

Kwiyubaka Ntabwo Bihitamo-Nibice byihariye

Kugaburira SMA ikora gusa kimwe no kuyishyiraho. Torque ifite akamaro - ariko nuburyo bukurikirana. Turerekana 7-9 muri-lb ibyuma bitagira umwanda, 5-7 muri-lb kumuringa. Ariko torque yonyine ntabwo izakosora insinga mbi. Ubujyakuzimu bugomba guhuza umuhuza wa dielectric guhagarara. Gukwirakwiza ibicuruzwa bigomba kuba bimwe - ntibigoretse, ntibirenze. N'umugurisha? Bajya * gusa * kumuyobora hanze - ntabwo ari ingabo ikingira, ntabwo ari file, ntabwo byombi. Ikosa rimwe ritangiza guhagarika kwerekana imbaraga aho kuyitanga.

Iyemezwa-ryukuri ririmo:

Ibi ntabwo birenze urugero. Nuburyo wirinda kumenya ko urubuga rwawe rwamasaha 24 rwatangiye kunanirwa saa tatu za mugitondo kuko umugabuzi umwe SMA yateje igihombo cya 12 dB kuri 3.5 GHz ijoro ryose.

Kwizerwa Bitangira Mbere Yambere Yambere ya Wrench

Zibo Jixiang Machinery Co., Ltd ntabwo ikora ibiryo bya SMA bihuza-kandi ntibizigera. Ubuhanga bwacu buri mu bimera bifatika, sisitemu yumye, hamwe no kuvanga asifalt-aho ubunyangamugayo bwibimenyetso bitarenze inzira yimitwaro yubatswe hamwe no gutembera kw'ibintu. Ariko twe * dukora * guhuza federasiyo ya SMA mumabati yacu yo kugenzura byikora, amarembo yo kurebera kure, hamwe na moderi ya televiziyo ya IoT. Kandi muri izo porogaramu, turerekana gusa ibiryo bya SMA byemewe byemewe na IPC-A-620 Icyiciro cya 3 kandi byageragejwe kuri IEC 60512-2-1.

Kuberako kwizerwa atari ikintu kiranga. Nibyingenzi. Nicyo kireka uruganda rwa beto rukora mumezi 18 adafite itumanaho rya PLC-ndetse no muri kariyeri iremereye ivumbi cyangwa uturere twa spray yumunyu. Niyo mpanvu uruganda rwacu rwa SjGZD060-3G rwumye rukomeza kugabanura neza muri ± 0.5% mugice cya 5.000, mugihe telemetrie ya RF ikomeza gufungirwa kumurongo wa SCADA rwagati.

Kugaburira SMA birenze ibyuma na plastiki. Numuhuza wambere mumurongo wizere - kuva sensor kugeza seriveri, kuva mubikoresho byumurima kugeza kubicu. Hitamo nkuko uhisemo urufatiro rwawe rufatika: hamwe nubushakashatsi bwuzuye, ibizamini byanditse, hamwe no kwihanganira zeru kubitandukanye.
