Feeder SMA yekubatanidza haingori chimwe chikamu cheRF-ndiwo mabhiza asina kusimba mumasaini ekugovera masisitimu uko kuvimbika kusingagone kutaurirana. Takavaona vachikundikana pasi pemabhasikoro ekupisa munzvimbo dzekunze dzezviteshi. Takavaona vachisimudza-pasina kukukurwa kana kurasikirwa-mushure menguva zviuru zvishanu zvekusangana mumalebhu ekuyedza mafoni. Uye takanzwa mainjiniya vachiti, *"Kana iyo yekudyisa SMA ikaramba yakagadzikana, iyo link yese inoramba ichizivikanwa."* Iyo haisi yekushambadzira hurukuro. Icho chokwadi chakasimbiswa mumunda.

Chii Chinoita Kuti Feeder SMA Iwedzere Kupfuura Kungobatanidza?

Iyo yekudyisa SMA haitsanangurwe nekubatanidza kwayo yakarukwa chete. Kuita kwayo kunotsamira pamatatu chaiwo-epasirese akasiyana: impedance kusachinja-chinja pama frequency mabhendi (kazhinji 50 Ω ± 0.3 Ω kubva kuDC kuenda ku18 GHz), kudzokororwa kwemuchina pasi pekudengenyeka, uye kusimba kwechimiro kurwisa oxidation uye galling. Kukundikana kwakawanda kwatakaona kwaisakonzerwa nekugadzira dhizaini-asi kusaenderana netambo prep, isingaenderane torque application, kana kushandisa isina-yakayerwa dielectric sleeve munzvimbo dzine hunyoro hwepamusoro.

Zvokwadi zvekudyisa-giredhi SMA zvibatanidza zvinoshandisa miviri yendarira-yakaputirwa nePTFE kana yakawedzerwa PTFE insulators-kwete generic polyethylene. Pini yepakati inofanirwa kuchengetedza <0.02 mm runout mushure mekudzokorora kukwirana. Kurasikirwa kwekupinza kunogara pazasi 0.15 dB pa6 GHz kana yaiswa zvakanaka. Kurasikirwa kwekudzoka kunodarika 30 dB kusvika ku12 GHz. Nhamba idzi dzine basa nekuti dzinobata zvakananga bit kukanganisa mwero mu5G fronthaul links uye kugadzikana kwechikamu muchikamu-chakarongeka radar feeds.

Isu tinoyedza batch yega yega kutarisana neMIL-STD-348B yeRF performance uye IEC 61169-10 yekutsungirira kwemichina. Hapana nzira dzekudimbudzira. Kwete "zvakanaka zvakakwana." Nekuti mune akagoverwa antenna masisitimu kana EMC bvunzo setups, imwe yepakati yekubatanidza inodonha musystem-level kusagadzikana.

Nei Yakajairwa SMA Isina Kukwana-Uye Zvekutsvagira panzvimbo

Vamwe vanogona kupokana kuti chero SMA yakanyorwa "RF giredhi" ichaita. Nekudaro, yakajairwa yekushambadzira SMA majoini anowanzo svetukira inodzorwa impedance kudzora munzvimbo yekuchinja, shandisa isingaenderane plating ukobvu, uye kushaya chinoteedzera zvitupa. Mukuita, izvo zvinoreva yakakwira VSWR spikes pamusoro pe8 GHz, kupindirana kusangana panguva yekuwedzera kupisa, uye kupfeka nguva isati yakwana mushure me1,200 kutenderera-kwete iyo zviuru zvishanu+ inotarisirwa mumishini-yakakosha feeder.

Kusiyana kunoonekwa munzvimbo nhatu:

Isu takatsiva anopfuura mazana maviri akakundikana egacy feeder mune telecom tower retrofits-uye nguva dzese, mudzi wechikonzero wakadzokera kune isingaenderane yekubatanidza-kune-tambo interface geometry, kwete antenna kana amplifier.

Kuisa Haisi Sarudzo-Iyo Chikamu cheSpecial

A feeder SMA inoita chete pamwe nekuiswa kwayo. Torque inokosha-asi ndizvo zvakaitawo kutevedzana. Isu tinotsanangura 7-9 in-lb yesimbi isina tsvina, 5-7 in-lb yendarira. Asi torque chete haigadzirise yakashata tambo prep. Kubvisa kudzika kunofanirwa kuenderana neiyo yekubatanidza dielectric kumira. Kufukidzwa kwebraid kunofanirwa kuve kwakafanana-kwete kumonyoroka, kwete kupindirana. Uye solder joints? Vanoenda * chete pamudhiraivha wekunze - kwete shield braid, kwete foil, kwete ese ari maviri. Imwe misstep inosuma discontinuities inoratidza simba pane kuriburitsa.

Kugadziriswa kwepasirese kunosanganisira:

Uku hakusi kunyanyisa. Ndiwo maitiro aunodzivisa kuwana yako 24-awa saiti yekumisikidza inotadza na3 am nekuti imwe feeder SMA yakagadzira gumi nemaviri dB yekurasikirwa nekudzoka pa3.5 GHz husiku.

Kuvimbika Kunotanga Pamberi Pekutanga Kutendeuka kweWrench

Zibo Jixiang Machinery Co., Ltd. haigadziri mafidha SMA majoini-uye haazombodaro. Hunyanzvi hwedu huri mukongiri batching zvidyarwa, yakaoma dhaka masisitimu, uye asphalt musanganiswa mhinduro - uko kutendeseka kwechiratidzo kunokosha zvishoma pane zvimiro zvemutoro nzira uye kuyerera kwezvinhu. Asi isu * tinoita * kubatanidza feeder SMA interfaces mune edu otomatiki ekudzora makabati, kure ekutarisa magedhi, uye IoT-inogonesa chirimwa telemetry modules. Uye mune izvo zvikumbiro, isu tinotsanangura chete feeder SMA zvikamu zvakasimbiswa kuIPC-A-620 Kirasi 3 uye yakaedzwa paIEC 60512-2-1.

Nekuti kuvimbika hachisi chinhu. Ndiyo yekutanga. Ndizvo zvinoita kuti simiti yekongiri ishande inoramba ichienderera kwemwedzi gumi nemisere isina PLC yekutaura inodonhedza-kunyangwe munzvimbo dzinorema guruva kana nzvimbo dzekupfapfaidza munyu. Ndosaka yedu SjGZD060-3G yakaoma dhaka chirimwa ichichengeta kurongeka kwedosing mukati me ± 0.5% mukati me5,000 mabhechi, nepo iri paboard RF telemetry inoramba yakakiyiwa pakati peSCADA node.

Feeder SMA inopfuura simbi nepurasitiki. Ndiyo yekutanga chinongedzo muketani yekuvimba-kubva sensor kuenda kune server, kubva kumunda mudziyo kuenda kune gore dashboard. Sarudza iyo senge iwe unosarudza nheyo yako kongiri: ine kuteedzera kuzere, kuyedzwa kwakanyorwa, uye zero kushivirira kune musiyano.
