Mu chip common mode inductor , zinthu zosiyanasiyana zitha kusankhidwa malinga ndi mawonekedwe ndi kukula kwake. Gv Electronics, fakitale ya chip inductor , imagawana nanu momwe mungasankhire koyilo yoyenera ya COMMon-mode kuchokera pamawonekedwe ake.
Mungafunike Izi Musanayambe Kuitanitsa
1. Momwe mungagwiritsire ntchito kufala kwa masiyanidwe ndi ma coils wamba wamba
Tisanafotokoze mawonekedwe a ma coils wamba omwe amatsamwitsa, tiyeni tiyambe tidziwitse lingaliro la siginecha wamba ndi ma siginolo osiyanitsira.
Kupatsirana kosiyana ndi njira yomwe imagwiritsidwa ntchito potumiza mwachangu kwambiri. Mwachitsanzo, MIPI? amagwiritsidwa ntchito mu kamera ndi chiwonetsero chazithunzi cha mafoni a m'manja, HDMI?, DisplayPort, ndi USB yamakompyuta onse ndi njira zopatsirana zosiyana.
M'mizere iwiri yopatsirana mosiyanasiyana, gawo la wina ndi mzake (losonyeza kupotozedwa kwa ma waveform amagetsi ndi mawonekedwe apano) ndikutembenuzidwa kwa ma siginecha.
Chizindikirochi chimatchedwa chizindikiro chosiyana, ndipo kutumiza kwa data kumachitika kudzera mu chizindikiro chosiyana. (Kusiyana kosiyana nthawi zina kumatchedwa njira yachibadwa). Poyerekeza ndi ma signature modes, palinso chizindikiro chotchedwa common mode sign, chomwe chimaperekedwa mugawo lomwelo mumizere iwiri.
Kwa ma chip common mode inductors a mizere yazizindikiro, chizindikiro chamtundu wamba ndi chizindikiro chosafunikira, ndiye kuti, phokoso, lomwe limatchedwa phokoso wamba.
Zizindikiro zamitundu yosiyanasiyana zimasakanizidwa ndi phokoso wamba. Chizindikiro chosiyanitsa chikalandiridwa, ma siginecha osiyanitsira amalimbitsana, ndipo phokoso lodziwika bwino limathetsa. Njira zosiyanasiyana zopatsirana ngati izi sizimakhudzidwa ndi phokoso wamba.
Zizindikiro zama radiation zomwe zimapatsirana mosiyanasiyana zimawonedwa patali, ndipo zizindikilo zimayikidwa pamwamba pa wina ndi mnzake. Panthawi imeneyi, zizindikiro zosiyanitsa zimasiyana, ndipo phokoso lamtundu wamba limalimbitsana. Ndiko kuti, amatha kumva phokoso wamba patali.
Pamene mavuto ofanana phokoso zimachitika, wamba mode kutsamwitsa koyilo chikugwirizana mu mndandanda kwa masiyanidwe kufala mzere bwino kuchotsa wamba mode phokoso.
2. Kuzindikira mawonekedwe a ma coils wamba amatsamwitsa
M'malo mwake, phokoso lamitundu yosiyanasiyana limachepetsedwa pang'ono chifukwa cha coil wamba wamba. Kuphatikiza apo, ma siginecha amitundu yosiyanasiyana komanso mawonekedwe wamba amatsika mosiyanasiyana chifukwa cha ma frequency osiyanasiyana. Makhalidwe amtundu wamba wotere amatsamwitsa koyilo amaimiridwa ndi mawonekedwe afupipafupi a kutayika koyikira kosiyana kwa Sdd21 ndi chizindikiro chodziwika bwino cha Scc21. (Sdd21 ndi Scc21 ndi gawo la magawo osakanikirana a 4-port S-parameters)
Mawonekedwe afupipafupi a kutayika kwamtundu wamba Scc21. Kuzama kwa kulowetsa kutayika, kutayika kwakukulu. Kukwera kwapang'onopang'ono kwa chizindikiro chosiyana, kutayika kwakukulu. Kutayika kwamtundu wamba wa Scc21 ndikopindika kokhala ndi nsonga, ndipo zotsatira zochotsa phokoso wamba zimasiyanasiyana kutengera pafupipafupi.
Mafupipafupi a chizindikiro cha chip common mode inductor ya mzere wamakina amasiyanasiyana kutengera mawonekedwe, ndipo mawonekedwe wamba amatsamwitsa koyilo nawonso amasintha molingana.
Kaya wamba mode tsamwitsa koyilo ndi oyenera akhoza kuweruzidwa molingana ndi kufala chizindikiro waveform. Nthawi zambiri, mafupipafupi odulidwa amtundu wamba amatsamwitsa koyilo ndi kuwirikiza katatu ma frequency azizindikiro za mafotokozedwe osiyanitsa. Zomwe zimatchedwa mafupipafupi a cutoff ndi ma frequency omwe kutayika kwa kuyika kosiyana kumakhala 3 dB.
Komabe, ngakhale zitakhala zosakwana nthawi za 3, pamakhala zovuta zambiri pamawonekedwe azizindikiro, ndipo izi ndizofotokozera bwino. (Chifukwa mulingo wamtundu wazizindikiro monga mapu obowola wafotokozedwa pa mawonekedwe aliwonse, pamapeto pake amaweruzidwa ngati ali oyenera kapena ayi molingana ndi muyezowu)
Kumbali imodzi, phokoso lamavuto ndi ma frequency ake amasiyanasiyana kuchokera ku terminal kupita ku terminal, ndipo molingana ndi mawonekedwe afupipafupi a kutayika koyenera koyikira koyenera amasintha moyenerera.
Mwachitsanzo, phokoso likachitika loposa mtengo wamalire wotchulidwa ndi mulingo woletsa kutulutsa mpweya, kumakhala kothandiza kwambiri kusankha yomwe ili ndi kutayika kokulirapo kwamtundu wamba mu bandi yafupipafupi ya phokosolo.
Kuphatikiza apo, phokoso lodziwika bwino lomwe limawonetsedwa ndi kufalikira kosiyana likhoza kusokoneza ntchito zake zoyankhulirana zopanda zingwe monga LTE ndi Wi-Fi. Zitha kuganiziridwa kuti phokoso lamtundu wamba la ma frequency omwewo monga kulumikizana opanda zingwe kumachitika, ndipo mlongoti umalandira phokosoli. Izi zimatchedwa kuponderezedwa reception sensitivity. Panthawiyi, poyika koyilo wamba yotsamwitsa, kutulutsa kwaphokoso wamba kumatha kuponderezedwa ndipo chidwi cholandirira chikhoza kusinthidwa.
Zomwe zili pamwambazi ndikuyambitsa mawonekedwe a SMD common mode inductors. Ngati mukufuna kudziwa zambiri za ma inductors a SMD, chonde titumizireni.
kuyang'anira kupanga mitundu yosiyanasiyana ya ma inductors amitundu, ma inductors okhala ndi mikanda, ma inductors ofukula, ma inductors a tripod, ma inductors a patch, ma inductors a bar, ma coils wamba, osintha ma frequency apamwamba ndi zida zina zamaginito.
