Attenuator ndi gawo lowongolera lomwe ntchito yake yayikulu ndikuchepetsa mphamvu yazizindikiro kudutsa pa attenuator. Pakugwiritsa ntchito, zowunikira za RF zimatha kugwira ntchito m'malo osiyanasiyana kutentha, zomwe zimapangitsa kuti lcryogenic fixed attenuators. Tapanga zoziziritsira kumadera otentha otsika (-269~+125 digiri Celsius) posankha zida zoyenera ndikuwongolera luso laukadaulo.

Ma Cryogenic fixed attenuators amakhala ndi matenthedwe abwino komanso okhazikika pamatenthedwe otsika kwambiri. Kumbali imodzi, microwave attenuator attenuator angagwiritsidwe ntchito ngati chizindikiro matalikidwe attenuators, ndipo mbali ina, millimeter wave attenuator angagwiritsidwe ntchito ngati mitsinje kutentha kwa kusamutsa ozizira. Mm wave attenuator atha kugwiritsidwa ntchito m'magawo monga kufufuza kwakuya kwamlengalenga, zakuthambo za wailesi, quantum computing, ndi kulumikizana opanda zingwe, makamaka pakuyesa kwafizikiki yotsika kwambiri komanso kafukufuku wa superconductor.

Cholinga:

1. Kuchepetsa kwa Signal: Cryogenic fixed attenuators amagwiritsidwa ntchito kuti achepetse molondola mphamvu ya RF ndi ma siginecha a microwave m'malo otentha kwambiri. Izi ndizofunikira poteteza zida zolandirira bwino komanso kuwongolera ma siginecha.
2. Kuwongolera Phokoso: Mwa kuchepetsa chizindikiro, phokoso ndi kusokoneza dongosolo kungachepetsedwe, motero kumapangitsa kuti chiŵerengero cha chizindikiro cha phokoso (SNR) chikhale bwino.
3. Kufananiza Impedance: Cryogenic fixed attenuators angagwiritsidwe ntchito kuti agwirizane ndi kusokonezeka kwa dongosolo, potero kuchepetsa kuwonetsetsa ndi mafunde oima ndikuwongolera machitidwe.

Ntchito:

1. Kuyesera kwa fizikiki ya Cryogenic: Pakuyesa kwafizikiki yotsika, ma cryogenic fixed attenuators amagwiritsidwa ntchito kuwongolera ndikusintha mphamvu yazizindikiro. Kuyesera kumeneku nthawi zambiri kumaphatikizapo kufufuza kwa superconductors, quantum computing ndi zochitika zina zotsika kutentha.
2. Kafukufuku wa Superconductor: Mu kafukufuku wa superconductor, ma cryogenic fixed attenuators amagwiritsidwa ntchito kuwongolera ndi kuwongolera ma frequency a radio ndi ma siginecha a microwave kuti aphunzire mawonekedwe ndi machitidwe a superconductors.
3. Quantum Computing: Mu makina a quantum computing, cryogenic fixed attenuator amagwiritsidwa ntchito kulamulira mphamvu ya chizindikiro ndi kuyanjana pakati pa quantum bits (qubits). Izi ndizofunikira kuti mukwaniritse magwiridwe antchito apamwamba kwambiri a quantum computing.
4. Astronomy ndi Radio Telescopes: M’kachitidwe ka zakuthambo ndi telesikopu ya wailesi, zoyambukirira za RF zimagwiritsidwa ntchito kusintha mphamvu za ma siginecha akuthambo olandiridwa. Izi zimathandiza kuwongolera bwino komanso kulondola kwa data yowonera.
5. Cryogenic Electronic Equipment: Pazida zamagetsi zotsika kutentha, microwave attenuator amagwiritsidwa ntchito kuwongolera ndikusintha mphamvu yazizindikiro kuti zitsimikizire kugwira ntchito moyenera komanso magwiridwe antchito apamwamba a zida.
Mwachidule, cryogenic fixed attenuators amagwiritsidwa ntchito kwambiri m'magawo ambiri monga kuyesa kwa fizikiki ya cryogenic, kafukufuku wa superconductor, quantum computing, astronomy, ndi cryogenic electronic equipment. Amawongolera magwiridwe antchito ndi kudalirika kwamakina powongolera mphamvu zama siginecha ndikuchepetsa phokoso.

Qualwaveimapereka ma attenuators osiyanasiyana olondola kwambiri a cryogenic omwe amaphimba ma frequency osiyanasiyana DC ~ 40GHz. Mphamvu yapakati ndi 2 watts. Ma attenuators amagwiritsidwa ntchito pazinthu zambiri pomwe kuchepetsa mphamvu kumafunikira.
