Li-Attenuators tse Fetohang tsa Waveguide

Lipotolohong tsa microwave, matla a lipontšo hangata a phahame haholo. Haeba matla a feteletseng a ke ke a laoloa ka botlalo, a tla baka mathata a mangata habonolo potolohong, joalo ka ho feta tekanyo e phahameng ea mamello ea matla a likarolo tsa potoloho le ho baka ho kheloha ho fapaneng. Ts'ebeliso ea li-attenuators tse feto-fetohang tsa waveguide li ka khahlametsa tlhokahalo ea ho fokotsa matla a lets'oao le ho netefatsa ts'ebetso e tloaelehileng ea lipotoloho tsa microwave.
Molao-motheo oa ts'ebetso oa attenuator o sa khaotseng o ipapisitse le litšobotsi tsa phatlalatso tsa maqhubu a motlakase ho li-waveguides. Haholo-holo e na le li-waveguides, lisebelisoa tse tsamaellanang le impedance, le li-block tsa conductor tse fapaneng. Ha lets'oao le feta har'a waveguide, karolo e 'ngoe ea matla e kenngoa ke "conductor block", ka hona e fokotsa matla a lets'oao.
Ha block conductor e le sebopeho sa mochini se ka lokisoang ke mosebelisi, ke li-attenuators tsa rotary. Li-attenuators tse feto-fetohang ka letsoho ke bathusi ba bohlokoahali lits'ebetsong tsa puisano tsa elektroniki.

Kopo:

1. Ho etsa bonnete ba ho leka-lekana ha litekanyetso tsa matšoao ka har'a ketane ea matšoao, li-attenuators tse fapaneng tsa waveguide li ka finyelloa ka ho fokotsa matla a pontšo.
2. Ho atolosa mefuta e mengata ea tsamaiso e boetse e le ntlha e matla ea rotary stepped attenuator, e ka netefatsang ts'ebetso e tsitsitseng ea tsamaiso.
3. Ho fana ka matching a impedance ho ka qoba pontšo ea pontšo le tahlehelo, ho netefatsa botsitso ba phetisetso ea matšoao.

The waveguide variable attenuator e sebelisoa haholo puisanong ea microwave le liteko tsa laboratori. E ka sebelisoa ho fetola matla a lets'oao ho fihlela litlhoko tse fapaneng. Ka mohlala, ka laboratoring, mohato oa rotary o ka fana ka bokhoni bo feto-fetohang ba ho fetola ha matla a lets'oao a hloka ho fetoloa ho sebetsa lisebelisoa tsa liteko. Puisanong ea microwave, li-attenuators tse sa khaotseng li ka sebelisoa ho lokisa matla a lets'oao ho netefatsa hore lets'oao ha le matla haholo kapa le fokola haholo nakong ea phetiso.
Melemo ea li-attenuators tse fapaneng ke bonolo, bonolo ba ts'ebeliso, le phetoho e bonolo. Ka ts'ebetso ea matsoho, basebelisi ba ka khona ho laola ka nepo palo ea ho fokotsa matšoao ha ho hlokahala. Leha ho le joalo, ha ho bapisoa le li-attenuators tsa waveguide tsa othomathike, mefuta e fapaneng ea tokiso ea li-attenuators tsa waveguide e ka ba tšesaane, mme ts'ebetso ea tokiso e hloka nako e itseng le ho nepahala.

Qualwavee fana ka VSWR e tlase le botenya bo phahameng ho tloha ho 0.96 ho isa ho 500GHz. Lebelo la ho fokotsa matla ke 0~40dB.
