Mfundo zazikuluzikulu ndi kugwiritsa ntchito mwatsopano kwa ma couplers otsogolera

Directional couplersNdizida zazikulu zomwe zimagwira ntchito mumayendedwe a RF ndi ma microwave, ndipo zimagwiritsidwa ntchito kwambiri powunikira ma siginecha, kugawa mphamvu ndi kuyeza. Mapangidwe awo anzeru amawathandiza kutulutsa zigawo za siginecha m'njira inayake popanda kusokoneza njira yayikulu yotumizira.

Mapulani mfundo zama couplers otsogolera

Directional couplersnthawi zambiri amakhala ndi mizere iwiri yotumizira kapena ma waveguide, ndipo amakwaniritsa njira yolumikizira mphamvu kudzera munjira inayake yolumikizirana. Mapangidwe wamba amaphatikiza awiri-hole waveguide couplers, microstrip line couplers, ndi zina zotero. Chofunikira kwambiri ndikukwaniritsa kulekanitsa bwino kwa mafunde akutsogolo ndi chakumbuyo poyang'anira ndendende kukula ndi katayanidwe ka mawonekedwe olumikizirana.

Kugwiritsa ntchito kwama couplers otsogolera

Kuwunika ndi kuyeza kwazizindikiro: Mu machitidwe a RF,ma couplers otsogoleraamagwiritsidwa ntchito kuchotsa mbali ya chizindikiro kuti iwunikire ndi kuyeza popanda kukhudza kutumiza kwa chizindikiro chachikulu. Izi ndizofunikira pakuwongolera dongosolo ndikuwunika magwiridwe antchito.

Kugawa mphamvu ndi kaphatikizidwe:Directional couplersimatha kugawa chizindikiro cholowera kumadoko angapo otulutsa, kapena kuphatikizira ma siginecha angapo kukhala chizindikiro chimodzi, ndipo imagwiritsidwa ntchito kwambiri pamakina a antenna ndi njira zoyankhulirana zamakina ambiri.

Kudzipatula ndi chitetezo: Nthawi zina,ma couplers otsogoleraamagwiritsidwa ntchito kupatula magawo osiyanasiyana ozungulira, kuteteza kusokoneza kwa ma sign kapena kulemetsa, ndikuteteza magwiridwe antchito a zida zovutirapo.

Kupita patsogolo kwaukadaulo kwaposachedwa

Ndi chitukuko chofulumira chaukadaulo wolumikizirana, mapangidwe ama couplers otsogoleraimapanganso zatsopano nthawi zonse. Mzaka zaposachedwa,ma couplers otsogolerakutengera zida zatsopano ndi ukadaulo wa micromachining apeza magulu ochulukira ogwiritsira ntchito pafupipafupi, kutayika kwapang'onopang'ono, komanso kuthekera kowongolera mphamvu. Kuonjezera apo, kachitidwe kaphatikizidwe ndi miniaturization kumapangitsa kuti zikhale zosavuta kuti otsogolera otsogolera alowe muzinthu zovuta zamagetsi, kukwaniritsa zofunikira za zipangizo zamakono zoyankhulirana zogwirira ntchito kwambiri komanso kupanga compact.

Mapeto

Monga gawo lofunikira mu machitidwe a RF ndi ma microwave,ma couplers otsogolerandizofunika kwambiri paukadaulo wamakono wolumikizirana chifukwa cha kapangidwe kake komanso kugwiritsa ntchito kwambiri. Ndi kupita patsogolo kosalekeza kwaukadaulo, ma couplers owongolera adzakhala ndi gawo lofunikira kwambiri pama frequency apamwamba, mphamvu zapamwamba komanso machitidwe ovuta kwambiri.
