Kumvetsetsa kufunikira kwa ma coaxial okhazikika - ma dummy katundu mu rf systems

Kuchotsa kochepa, komwe kumadziwikanso kuti katundu wambiri, ndi chida chogwiritsidwa ntchito mu electrine engider kuti ayesere katundu wamagetsi osasungunula mphamvu. Imakhala ndi chinthu chosiyana ndi chitsulo chomwe chimalumikizidwa ndi chingwe cholumikizira chipika. Cholinga cha kutha kwa coaxial kokhazikika ndikuyamwa radio pafupipafupi (RF) ndikupewa kuwonetsedwa mdera.

Katundu wa Dummy amagwiritsidwa ntchito pogwiritsa ntchito zinthu zosiyanasiyana, monga poyesa ndi kuyeza kwa wailesi yaziilesi, a nthawi ya apulogalamu, ndi antennasi. Popereka mafayilo okhazikika pamtunda wa chipangizocho poyesedwa, katundu wa Dummy amatsimikizira kuti rf mphamvu imayamba kusokoneza kapena kuwonongeka kwa zida. Izi ndizofunikira kwambiri pa gawo loyesa zida zamagetsi kuti ziteteze zizindikiro zomwe zitha kusokoneza kulondola kwa miyezo.

Kuphatikiza pa kuyesa ndi kutchuka, ma coaxial okhazikika kumagwiritsidwanso ntchito mu RF ndi microwave Madongosolo kuti athetse mizere yogwiritsidwa ntchito potumiza, kupewa ziwonetserozi ndikusungabe chizindikiro. Mapulogalamu apamwamba kwambiri, monga mu mafoni am'manja ndi machitidwe a rammy, kugwiritsa ntchito katundu wambiri kumathandiza kuchepetsa kuchepa kwa signal.

Mapangidwe a kusokonekera kwa coaxial okhazikika ndikofunikira pakuchita kwake, ndi zinthu monga zofananira, mphamvu yogwiritsira ntchito mphamvu, komanso pafupipafupi pakugwira ntchito yofunika kwambiri pakugwira ntchito kwake. Mitundu yosiyanasiyana yazomwe zimasaka zokongoletsera zokoka za coaxial zilipo, kuphatikizapo zopendekera komanso zopindulitsa, iliyonse imayenererana ndi ntchito zawo potengera mawonekedwe awo.

Pomaliza, ma cummy okhazikika okhazikika ndi zinthu zofunika kwambiri mu RF ndi microwave machitidwe, kupereka zodalirika komanso zokhazikika kumatanthawuza kumangirirani katundu wamagetsi ndikutenga mphamvu ya rf. Pogwiritsa ntchito katundu wambiri poyeserera ndi njira zoyeserera, mainjiniya amatha kulondola komanso kugwiritsa ntchito zida zamagetsi, pamapeto pake zidapangitsa kuti pakhale magwiridwe antchito komanso kudalirika mu magetsi.
