Coaxial Isolator
RF coaxial isolator ndi chipangizo chomwe chimagwiritsidwa ntchito kupatula ma siginecha mumayendedwe a RF.Ntchito yake yayikulu ndikutumiza bwino zizindikiro ndikuletsa kusinkhasinkha ndi kusokoneza.Ntchito yayikulu ya RF coaxial isolator ndikupereka ntchito zodzipatula komanso zodzitetezera pamakina a RF.M'machitidwe a RF, zizindikiro zina zowonetsera zikhoza kupangidwa, zomwe zingakhale ndi zotsatira zoipa pa kayendetsedwe ka kayendetsedwe kake.RF coaxial isolators imatha kupatulira bwino ma siginecha owonetseredwawa ndikuwalepheretsa kusokoneza kufalitsa ndi kulandira chizindikiro chachikulu.
Mfundo yogwirira ntchito ya RF coaxial isolators imatengera machitidwe osasinthika a maginito.Zida zamaginito zomwe zili mkati mwa isolator zimatenga ndikusintha mphamvu ya maginito ya siginecha yowonetsedwa, ndikuisintha kukhala mphamvu yotentha kuti iwonongeke, potero kulepheretsa chizindikiro chowonekera kuti chibwerere ku gwero.

Pitani ku Isolator
Drop-in isolator imalumikizidwa ndi zida za zida kudzera pa riboni.Nthawi zambiri, digiri yodzipatula ya Drop-in isolator imodzi imakhala pafupifupi 20dB.Ngati digiri yapamwamba yodzipatula ikufunika, zodzipatula zapawiri kapena zingapo zitha kugwiritsidwanso ntchito kukwaniritsa digiri yapamwamba yodzipatula.Mapeto achitatu a Drop-in isolator adzakhala ndi attenuation chip kapena RF resistor.Drop-in isolator ndi chipangizo choteteza chomwe chimagwiritsidwa ntchito pamakina amtundu wa wailesi, chomwe ntchito yake yayikulu ndikutumiza ma siginecha m'njira yosagwirizana kuti ma sign akumapeto a mlongoti asabwererenso kumapeto.

Broadband Isolator
Zodzipatula za Broadband ndizofunikira kwambiri pamakina olankhulirana a RF, zomwe zimapereka zabwino zambiri zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana.Izi zodzipatula zimapereka kuphimba kwa Broadband kuti zitsimikizire kuti zikuyenda bwino pama frequency osiyanasiyana.Ndi luso lawo lolekanitsa ma siginecha, amatha kupewa kusokonezedwa ndi ma siginecha a bandi ndikusunga kukhulupirika kwa ma siginecha.
Chimodzi mwazabwino zazikulu za ma Broadband Isolators ndikuchita bwino kwambiri kudzipatula.Amalekanitsa bwino chizindikiro kumapeto kwa mlongoti, kuonetsetsa kuti chizindikiro chomwe chili kumapeto kwa mlongoti sichikuwonekera mu dongosolo.Nthawi yomweyo, zodzipatula izi zimakhala ndi mawonekedwe abwino a mafunde a doko, kuchepetsa ma siginecha owoneka bwino ndikusunga kufalikira kwa ma siginecha okhazikika.

Dual Junction Isolator
Chodzipatula chapawiri-junction ndi chipangizo chomwe chimangogwiritsidwa ntchito nthawi zambiri mu ma microwave ndi ma millimeter-wave frequency band kuti azipatula ma siginecha owoneka kuchokera kumapeto kwa tinyanga.Amapangidwa ndi kapangidwe ka awiri odzipatula.Kutayika kwake kuyika ndi kudzipatula nthawi zambiri kumakhala kowirikiza kawiri kuposa kwa chodzipatula chimodzi.Ngati kudzipatula kwa wodzipatula m'modzi ndi 20dB, kudzipatula kwa cholumikizira chapawiri-pawiri kumatha kukhala 40dB.Kuyima kwa doko sikusintha kwambiri.
M'dongosolo, pamene chizindikiro cha mawayilesi amaperekedwa kuchokera ku doko lolowera kupita ku mphambano ya mphete yoyamba, chifukwa mbali imodzi ya mphambano yoyamba ya mphete imakhala ndi ma radio frequency resistor, chizindikiro chake chimatha kuperekedwa kumapeto kwachiwiri. mphambano ya mphete.Chigawo chachiwiri cha loop ndi chofanana ndi choyamba, chokhala ndi ma RF resistors, chizindikirocho chidzaperekedwa ku doko lotuluka, ndipo kudzipatula kudzakhala chiwerengero cha kudzipatula kwa magawo awiri a loop.Chizindikiro chowonekera chomwe chikubwerera kuchokera ku doko lotulutsa chidzayankhidwa ndi RF resistor mu mphambano yachiwiri ya mphete.Mwanjira imeneyi, kudzipatula kwakukulu pakati pa madoko olowera ndi kutulutsa kumatheka, kuchepetsa kuwunikira komanso kusokoneza dongosolo.

SMD Isolator
SMD isolator ndi chipangizo chodzipatula chomwe chimagwiritsidwa ntchito kulongedza ndikuyika pa PCB (bolodi losindikizidwa).Amagwiritsidwa ntchito kwambiri pamakina olumikizirana, zida za microwave, zida zamawayilesi, ndi magawo ena.Zodzipatula za SMD ndi zazing'ono, zopepuka, komanso zosavuta kuziyika, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito makina ophatikizika kwambiri.Zotsatirazi zipereka chitsogozo chatsatanetsatane cha mawonekedwe ndi kugwiritsa ntchito kwa zodzipatula za SMD.
Choyamba, zodzipatula za SMD zimakhala ndi kuthekera kosiyanasiyana kwa ma frequency band.Nthawi zambiri amaphimba ma frequency osiyanasiyana, monga 400MHz-18GHz, kuti akwaniritse zofunikira pafupipafupi pamapulogalamu osiyanasiyana.Kuthekera kokulirapo kwa band pafupipafupi kumathandizira odzipatula a SMD kuti azichita bwino kwambiri pazogwiritsa ntchito zingapo.
