Ma Waveguide Variable Attenuators Amayendetsedwa Mozungulira Mosalekeza ndi Manja

Mu ma microwave circuits, mphamvu ya ma signals nthawi zambiri imakhala yokwera kwambiri. Ngati mphamvu yochulukirapo singathe kulamulidwa mokwanira, ingayambitse mavuto ambiri mu circuits, monga kupitirira mphamvu yayikulu yomwe zigawo za circuit zimalolera komanso kuyambitsa kusintha kosiyanasiyana. Kugwiritsa ntchito ma waveguide variable attenuators kungathandize kuchepetsa mphamvu ya signals ndikuwonetsetsa kuti ma microwave circuits akuyenda bwino.
Mfundo yogwirira ntchito ya continuous variable attenuator imachokera pa makhalidwe a mafunde a electromagnetic mu ma waveguides. Makamaka imakhala ndi ma waveguides, zipangizo zofananira ndi impedance, ndi ma variable conductor blocks. Pamene chizindikiro chikudutsa mu waveguide, gawo lina la mphamvu limatengedwa ndi conductor block, motero kuchepetsa mphamvu ya chizindikiro.
Ngati chipika cha kondakitala chili ndi kapangidwe ka makina komwe kangasinthidwe ndi wogwiritsa ntchito, chimakhala chochepetsera mpweya chozungulira. Zochepetsera mpweya zosinthika pamanja ndi zothandiza kwambiri pamakina olumikizirana zamagetsi.
