The Attenuator ndi gawo lamagetsi lomwe limagwiritsidwa ntchito kwambiri pazida zamagetsi, ndipo ntchito yake yayikulu ndikupereka attenuation. Ndi chinthu chowononga mphamvu, chomwe chimasanduka kutentha pambuyo pogwiritsira ntchito mphamvu. Zolinga zake zazikulu ndi izi: (1) Sinthani kukula kwa chizindikiro mu dera; (2) Poyerekeza njira kuyeza dera, angagwiritsidwe ntchito kuwerenga mwachindunji attenuation mtengo wa netiweki anayesedwa; (3) Konzani zofananira za impedance, ngati mabwalo ena amafunikira Pamene choletsa chokhazikika chokhazikika chikugwiritsidwa ntchito, chothandizira chimatha kuyikidwa pakati pa chigawocho ndi choyimitsa chenichenicho kuti chiteteze kusintha kwa impedance. Ndiye mukamagwiritsa ntchito chochepetsera, ndi zinthu ziti zomwe zikufunika chisamaliro?
Tiyeni tifotokoze mwatsatanetsatane pansipa:
1. Kuyankha pafupipafupi: kuchuluka kwa bandiwifi, komwe kumawonetsedwa mu megahertz (MHz) kapena gigahertz (GHz). Othandizira zolinga nthawi zambiri amakhala ndi bandwidth pafupifupi 5 GHz, yokhala ndi bandwidth yopitilira 50 GHz.
2. Kuchepetsa ndi kapangidwe:
Chiyerekezo chochepetsetsa chimatanthawuza kuchepetsedwa, nthawi zambiri kuyambira 3dB, 10dB, 14dB, 20dB, mpaka 110dB. Njira yochepetsera ndi: 10lg (zolowera/zotulutsa), mwachitsanzo: mawonekedwe a 10dB: kulowetsa: kutulutsa = kuchepetsa kambiri = nthawi 10. Kapangidwe kake kamakhala kogawidwa m'mitundu iwiri: chowongolera chokhazikika komanso chowongolera chosinthika. Attenuator Yokhazikika imatanthawuza chochepetsera chokhala ndi chiyerekezo chokhazikika chochulukira mumitundu ina ya ma frequency. Step attenuator ndi chochepetsera chomwe chili ndi mtengo wake wokhazikika komanso chiŵerengero chofanana chosinthika. Iwo lagawidwa pamanja sitepe attenuator ndi programmable sitepe attenuator.
3. Fomu yolumikizira mutu ndi kukula kwa kulumikizana:
Mtundu wolumikizira umagawidwa mu mtundu wa BNC, mtundu wa N, mtundu wa TNC, mtundu wa SMA, mtundu wa SMC, ndi zina. Pa nthawi yomweyo, mawonekedwe olumikizira ali ndi mitundu iwiri: wamwamuna ndi wamkazi.
Kukula kolumikizana kumagawidwa m'magulu a metric ndi mfumu, ndipo zomwe zili pamwambazi zimatsimikiziridwa malinga ndi zofunikira zogwiritsira ntchito; ngati mitundu yolumikizira ikufunika kulumikizidwa, ma adapter olumikizana nawo amatha kukhala ndi zida, mwachitsanzo: BNC mpaka N-mtundu cholumikizira, etc.
4. Attenuation index:
Zizindikiro za attenuation zili ndi zofunika zambiri, makamaka zotsatirazi: kulondola kwanthawi yayitali, kupirira mphamvu, kulepheretsa mawonekedwe, kudalirika, kubwerezabwereza, ndi zina.
Monga wopanga waattenuators, Jingxin akhoza kukuthandizani ndi mitundu yosiyanasiyana ya attenuators malinga ndi yankho lanu la RF.
