Tus attenuator yog ib qho khoom tswj uas nws lub luag haujlwm tseem ceeb yog txo qhov muaj zog ntawm lub teeb liab uas hla dhau tus attenuator. Hauv kev siv tiag tiag, RF attenuators tuaj yeem ua haujlwm hauv qhov chaw kub sib txawv, ua rau muaj lcryogenic fixed attenuators. Peb tau tsim cov attenuators rau qhov chaw kub qis (-269 ~ + 125 degrees Celsius) los ntawm kev xaiv cov khoom siv raw thiab txhim kho qib thev naus laus zis.

Cov attenuators ruaj khov cryogenic muaj cov thermal conductivity zoo thiab ruaj khov siab ntawm qhov kub qis heev. Ntawm ib sab tes, microwave attenuator tuaj yeem siv ua cov teeb liab amplitude attenuators, thiab ntawm qhov tod tes, millimeter wave attenuator tuaj yeem siv ua cov cua sov rau kev hloov pauv txias. Mm wave attenuator tuaj yeem siv rau hauv cov teb xws li kev tshawb nrhiav qhov chaw tob, xov tooj cua astronomy, quantum computing, thiab kev sib txuas lus wireless, tshwj xeeb tshaj yog hauv kev sim physics kub qis thiab kev tshawb fawb superconductor.

Lub Hom Phiaj:

1. Kev Txo Qhov Teeb Meem: Cov khoom siv kho kom ruaj khov cryogenic siv los txo qhov muaj zog ntawm cov teeb liab RF thiab microwave hauv qhov chaw kub qis heev. Qhov no yog qhov tseem ceeb rau kev tiv thaiv cov khoom siv tau txais rhiab heev thiab tswj cov teeb liab.
2. Kev Tswj Suab Nrov: Los ntawm kev txo qhov teeb liab, lub suab nrov thiab kev cuam tshuam hauv lub kaw lus tuaj yeem txo qis, yog li txhim kho qhov piv ntawm lub teeb liab rau lub suab nrov (SNR) ntawm lub teeb liab.
3. Kev Sib Tw Impedance: Cov attenuators ruaj khov cryogenic tuaj yeem siv los sib phim qhov impedance ntawm lub kaw lus, yog li txo cov kev cuam tshuam thiab cov nthwv dej sawv ntsug thiab txhim kho kev ua haujlwm ntawm lub kaw lus.

Daim Ntawv Thov:

1. Kev sim ua physics cryogenic: Hauv kev sim physics kub qis, cov attenuators cryogenic ruaj khov yog siv los tswj thiab kho qhov muaj zog ntawm lub teeb liab. Cov kev sim no feem ntau cuam tshuam nrog kev kawm txog superconductors, kev suav lej quantum thiab lwm yam xwm txheej kub qis.
2. Kev Tshawb Fawb Txog Superconductor: Hauv kev tshawb fawb txog superconductor, cov attenuators uas ruaj khov cryogenic siv los kho thiab tswj cov teeb liab xov tooj cua thiab microwave kom kawm txog cov yam ntxwv thiab tus cwj pwm ntawm cov superconductors.
3. Kev Xam Xaj Quantum: Hauv cov txheej txheem xam xaj quantum, cov khoom siv cryogenic fixed attenuator siv los tswj lub zog ntawm lub teeb liab thiab kev sib cuam tshuam ntawm cov quantum bits (qubits). Qhov no yog qhov tseem ceeb rau kev ua tiav cov haujlwm xam xaj quantum siab.
4. Kev Tshawb Fawb Txog Hnub Qub thiab Xov Tooj Cua: Hauv cov txheej txheem tshawb fawb txog hnub qub thiab xov tooj cua, cov RF attenuators raug siv los kho lub zog ntawm cov teeb liab saum ntuj ceeb tsheej uas tau txais. Qhov no pab txhim kho qhov zoo thiab qhov tseeb ntawm cov ntaub ntawv soj ntsuam.
5. Cov Khoom Siv Hluav Taws Xob Cryogenic: Hauv cov khoom siv hluav taws xob uas tsis kub, lub tshuab microwave attenuator siv los tswj thiab kho lub zog ntawm lub teeb liab kom ntseeg tau tias kev ua haujlwm ib txwm thiab kev ua haujlwm siab ntawm cov khoom siv.
Hauv ntej, cov attenuators ruaj khov cryogenic siv dav hauv ntau qhov chaw xws li kev sim physics cryogenic, kev tshawb fawb superconductor, kev suav quantum, astronomy, thiab cov khoom siv hluav taws xob cryogenic. Lawv txhim kho kev ua haujlwm ntawm lub kaw lus thiab kev ntseeg siab los ntawm kev tswj lub zog teeb liab thiab txo cov suab nrov.

Qualwavemuab ntau yam kev ntsuas siab cryogenic ruaj khov attenuators npog qhov zaus ntau DC ~ 40GHz. Lub zog nruab nrab yog 2 watts. Cov attenuators siv rau hauv ntau daim ntawv thov uas xav tau txo qis zog.
