Li-Attenuator tse Fetohang tsa Waveguide
Lipotolohong tsa microwave, matla a matshwao hangata a phahame haholo. Haeba matla a feteletseng a ke ke a laolwa ka botlalo, a tla baka mathata a mangata habonolo potolohong, jwalo ka ho feta mefuta e phahameng ka ho fetisisa ya mamello ya matla ya dikarolo tsa potoloho le ho baka diphapang tse fapaneng. Tshebediso ya di-attenuator tse feto-fetohang tsa waveguide e ka kgotsofatsa tlhoko ya ho fokotsa matla a matshwao le ho netefatsa tshebetso e tlwaelehileng ya dipotoloho tsa microwave.
Molao-motheo oa ho sebetsa oa attenuator e feto-fetohang e tsoelang pele o ipapisitse le litšobotsi tsa ho ata ha maqhubu a motlakase ho li-waveguide. Haholo-holo e na le li-waveguide, lisebelisoa tse bapisang impedance, le li-conductar block tse feto-fetohang. Ha lets'oao le feta ka har'a waveguide, karolo ea matla e monngoa ke block ea conductor, ka hona e fokotsa matla a lets'oao.
Ha boloko ea mokhanni e le sebopeho sa mechini se ka fetoloang ka letsoho ke mosebelisi, ke li-attenuator tse potolohang tse nang le mehato e potolohang. Li-attenuator tse feto-fetohang ka letsoho ke bathusi ba bohlokoa litsamaisong tsa puisano tsa elektroniki.
Kopo:
1. Ho netefatsa hore maemo a lets'oao a leka-lekane ketane ea lets'oao, li-attenuator tse feto-fetohang tsa tataiso ea maqhubu li ka finyelloa ka ho fokotsa matla a lets'oao.
2. Ho atolosa mefuta e fapaneng ea sistimi le hona ke ntlha e matla ea attenuator e potolohang, e ka netefatsang ts'ebetso e tsitsitseng ea sistimi.
3. Ho fana ka ho bapisa impedance ho ka qoba ho bonahatsa le ho lahleheloa ke lets'oao, ho netefatsa botsitso ba phetiso ea lets'oao.
Setlamo se feto-fetohang sa waveguide se sebediswa haholo puisanong ya microwave le ditekong tsa laboratori. Se ka sebediswa ho fetola matla a letshwao ho fihlela ditlhoko tse fapaneng. Mohlala, laboratoring, mohato o potolohang o ka fana ka bokgoni ba ho fetola bo tenyetsehang ha matla a letshwao a hloka ho fetolwa ho leka tshebetso ya disebediswa. Puisanong ya microwave, ditlamo tse feto-fetohang tse sa fetoheng di ka sebediswa ho fetola matla a letshwao ho netefatsa hore letshwao ha le matla haholo kapa ha le fokola haholo nakong ya phetiso.
Melemo ea li-attenuator tse feto-fetohang ke bonolo, bonolo ba tšebeliso, le tokiso e tenyetsehang. Ka ts'ebetso ea letsoho, basebelisi ba ka laola ka nepo palo ea ho fokotsa lets'oao ha ho hlokahala. Leha ho le joalo, ha ho bapisoa le li-attenuator tsa waveguide tse iketsang, mefuta ea tokiso ea li-attenuator tsa waveguide tse tsamaisoang ka letsoho e ka ba nyane, 'me ts'ebetso ea tokiso e hloka nako e itseng le ho nepahala.
Qualwavee fana ka VSWR e tlase le ho batalatsa ho hoholo ha mocheso ho tloha ho 0.96 ho isa ho 500GHz. Sebaka sa ho fokotsa mocheso ke 0 ~ 40dB.
