Kutha kwa Mafunde a Mphamvu Yapakati

Kutha kwa Medium Power Waveguide ndi gawo lopanda mphamvu lomwe limagwiritsidwa ntchito kuyamwa zizindikiro za microwave zamphamvu yapakatikati. Ndi lofanana ndi katundu wa waveguide wamphamvu yochepa ndipo limagwiritsidwa ntchito kuteteza magwiridwe antchito abwinobwino a zigawo zina mumakina a microwave, kupewa kuwunikira kwa chizindikiro, ndikuwonjezera kukhazikika kwa dongosolo. Komabe, poyerekeza ndi katundu wa waveguide wamphamvu yochepa, ma waveguide terminals amphamvu kwambiri amatha kuyamwa zizindikiro za microwave zamphamvu kwambiri kuyambira 100 watts mpaka 1 kilowatt, ndi ma frequency range a mazana angapo a megahertz mpaka 110GHz. Chifukwa cha kutayika kwa mphamvu kwakukulu kwa katundu wa waveguide wamagetsi apakatikati, kutentha kwawo kwamkati kumakhala kwakukulu. Kuti tipewe kuwonongeka kwa katundu kapena kutenthedwa kwambiri, chotenthetsera nthawi zambiri chimafunika kuti chichotse kutentha. Ubwino wa RF Termination umatsimikiziridwa ndi zinthu monga mphamvu yoyesedwa, kutentha kogwirira ntchito, bandwidth ya pafupipafupi, ndi kuyanjana.

Katundu wa Medium Power Waveguide Load uli ndi makhalidwe awa:

1. Kukana mphamvu kwambiri: Kutha kwa Medium Power Waveguide kwapangidwa kuti kupirire ma microwave signaling pamlingo wa mphamvu yapakati. Kumatha kukhalabe kolimba pansi pa katundu wa ma signal amphamvu kwambiri, kupewa kupitirira muyeso ndi kuwonongeka.
2. Kuchuluka kwa kuwala koyenera: Kutha kwa Microwave Medium Power Waveguide kumakhala ndi kuchuluka kwa kuwala koyenera kumapeto kwa waveguide. Kumawonetsa bwino chizindikiro chomwe chili mkati mwa waveguide kubwerera kumapeto kwa gwero, zomwe zimalepheretsa chizindikirocho kupitiliza kufalikira kumapeto kwa katundu.
3. Broadband: Medium Power Waveguide Kutha kwa mafunde kumatha kugwira ntchito pa ma frequency ambiri ndipo ndikoyenera machitidwe osiyanasiyana a microwave okhala ndi ma frequency osiyanasiyana.

Kutha kwa Medium Power Waveguide kumagwiritsidwa ntchito m'magawo otsatirawa:

1. Kulankhulana kwa microwave: Mphamvu Yapakati Yogwiritsa Ntchito Mafunde ingagwiritsidwe ntchito m'maukonde a mafunde m'makina olumikizirana a microwave, zomwe zimapangitsa kuti mafunde a impedance azigwirizana komanso kuti zizindikiro zisagwiritsidwe ntchito zithe bwino. Zingathandize kuti makina azigwira bwino ntchito ndikuchepetsa kusokoneza kwa mafunde.
2. Chotumizira ndi cholandirira cha microwave: Chitsogozo cha Mafunde Chapakati Choletsa kugwiritsa ntchito magetsi chingagwiritsidwe ntchito poika ma terminal a ma microwave transmitters ndi olandirira magetsi. Chimatha kuyamwa bwino mphamvu ya chizindikiro cholowera, kupewa kuwunikira kwa chizindikiro ndi kusokoneza zida zina zamagetsi.
3. Kuyesa ndi kuyeza kwa microwave: Kutha kwa RF kumagwiritsidwa ntchito kwambiri poyesa ndi kuyeza microwave, zomwe zimapangitsa kuti zida ziyesedwe bwino. Kumatha kuteteza zida zoyesera kuti zisawonongeke ndi zizindikiro zamagetsi zambiri komanso kupereka zotsatira zolondola zoyesera.
4. Chowonjezera mphamvu cha microwave RF: Kutha kwa microwave kungagwiritsidwe ntchito ngati chotulutsira mphamvu kuti kuthetsere katundu wa chowonjezera mphamvu cha microwave RF. Chimatha kuyamwa mphamvu ya chizindikiro chotulutsira mphamvu cha amplifier, kupewa kuwunikira kwa chizindikiro ndi kuwonongeka kwa chowonjezeracho.
