Chochepetsera Chosinthika, 0.02~18GHz, Kuchepetsa Range 0~63.75dB, Gawo 0.25dB

Monga gawo lofunikira kwambiri mu machitidwe oyesera ndi kulumikizana kwa microwave, Programmable Attenuator imasintha bwino kuchuluka kwa chizindikiro cha microwave mwa kuwongolera netiweki yotsutsa yolondola yamkati kudzera mu malamulo a digito. Phindu lake lalikulu lili m'malo mwa zotchingira zamanja zachikhalidwe, kupereka kuwongolera kwa chizindikiro chodziwikiratu komanso cholondola kwambiri mkati mwa gulu lalikulu la ma frequency kuti ikwaniritse zosowa za machitidwe amakono amagetsi kuti agwire ntchito patali komanso mwachangu. Izi ndi mawu oyamba mwatsatanetsatane ochokera mbali ziwiri: mawonekedwe ake akuluakulu azinthu ndi madera akuluakulu ogwiritsira ntchito.

Makhalidwe:

1. Kulondola kwambiri komanso sitepe yopyapyala: Chogulitsachi chili ndi sitepe yocheperako ya 0.25dB, zomwe zimathandiza kusintha kwa ma amplitude a chizindikiro. Kuchuluka kwa kuchepetsedwa kwa chizindikiro kumafika pa 63.75dB, komwe kumakhudza mitundu yosiyanasiyana kuyambira pa ma signali ofooka mpaka amphamvu. Kulondola kwake kwa kuchepetsedwa kwa chizindikiro kumatha kufika ±2dB, kuonetsetsa kuti kulondola komanso kubwerezabwereza kumatheka pansi pa makonda osiyanasiyana.
2. Kuphimba kwa ma frequency a Ultra-wideband: Kuzungulira kwa ma frequency ogwirira ntchito kuyambira 0.02GHz mpaka 18GHz, kumakhudza pafupifupi ma bandwidth onse ofunikira olumikizirana ndi radar. Kuphimba kwa ma frequency ochulukirapo kumeneku kumalola kuti igwire ma signal m'ma band osiyanasiyana papulatifomu imodzi, kuchotsa kufunikira kosintha zida zingapo.
3. Kutayika kochepa kwa ma insertion ndi kufananiza bwino: Kutayika kwakukulu kwa ma insertion kumayendetsedwa mkati mwa 8dB, kuchepetsa kugwiritsa ntchito mphamvu ya chizindikiro choyambirira. Pakadali pano, chiŵerengero chachikulu cha mafunde oyima a voltage a ma input and output ports ake ndi 2.0, kuonetsetsa kuti ma impedance akugwirizana bwino ndi machitidwe a 50Ω, kuchepetsa bwino ma signal reflections ndikutsimikizira kukhulupirika kwa ma signal transmission.
4. Kuwongolera kodalirika kokonzedwa komanso kapangidwe kake: Chogulitsachi chimathandizira kuwongolera kutali kudzera pa ma interfaces wamba, zomwe zimathandiza kuphatikizana mu makina oyesera okha. Mapangidwe ena amaganiziranso kusinthasintha kwa chilengedwe, kusunga magwiridwe antchito okhazikika pa kutentha kwakukulu.

Mapulogalamu:

1. Kuyesa kwa makina olumikizirana: Mu kafukufuku ndi chitukuko ndi kupanga malo oyambira a 5G, malo olumikizirana a satellite, ndi makina a radar, chida ichi chimagwiritsidwa ntchito kwambiri kuyerekezera kutayika kwa ma signal mumlengalenga.
2. Makina oyesera okha: Monga gawo lofunikira kwambiri pakukonza chizindikiro mu makina a ATE, imatha kuwongolera molondola momwe chizindikirocho chimalowera ku zida monga ma spectrum analyzer, ma signal generator, kapena ma power meter. Izi sizimangoletsa kuwonongeka kwa zida zoyesera zodula chifukwa cha mphamvu yochulukirapo ya chizindikiro komanso zimawonetsetsa kuti miyeso imatengedwa pamlingo woyenera wa chizindikiro, potero zimakweza mphamvu yosinthika komanso kulondola kwa muyeso wa makina onse oyesera.
3. Kuyesa kwa zigawo ndi mzere wopanga: Poyesa kupanga zinthu zambiri za RF ndi microwave, chipangizochi chimagwiritsidwa ntchito mwachangu komanso molondola kuchita kutsimikizira magwiridwe antchito ndikuwunika magwiridwe antchito. Mwa kusintha mphamvu ya chizindikiro cholowera chokha, kamvekedwe ka yankho la chipangizocho chomwe chikuyesedwa pansi pa mikhalidwe yosiyanasiyana ya chizindikirocho kangathe kujambulidwa bwino.
4. Kafukufuku ndi zoyeserera zamaphunziro: Mu ma laboratories a microwave a mayunivesite ndi mabungwe ofufuza, ndi gawo lofunikira kwambiri popanga nsanja zoyesera zoyeserera njira ndi kafukufuku wofalitsa mafunde, kuthandiza ofufuza kutsanzira malo ovuta amagetsi ndikutsimikizira zitsanzo ndi mapangidwe a malingaliro.

Qualwave Inc. imapereka intaneti yothamanga kwambiri komanso yosinthasinthazochepetsera mapulogalamundi ma frequency mpaka 40GHz. Gawoli likhoza kufika pa 0.5dB, ndipo kuchuluka kwa attenuation kungafike pa 80dB kapena kupitirira apo. Nkhaniyi ikubweretsa attenuator yokonzedwa ya 0.02~18GHz yokhala ndi kuchuluka kwa attenuation ya 0~63.75dB ndi gawo la 0.25dB.
