Hostenator yog kev tswj hwm cov khoom uas nws lub luag haujlwm tseem ceeb yog txhawm rau txo lub teeb liab lub zog dhau los ntawm Hwjtim. Hauv kev siv cov tswv yim, RF HOSTUELSt cov haujlwm tuaj yeem ua haujlwm nyob rau hauv qhov chaw kub sib txawv, muab nce mus rau LrCyogenic taag delenuics. Peb muaj cov tswv yim zoo rau cov neeg muaj ib puag ncig tsawg (-269 ~ + 125 degrees Celsius) los ntawm kev xaiv cov khoom siv raw thiab txhim kho qib kev thev naus laus zis.

Cryogenic taag delenuat muaj cov khoom siv hluav taws xob zoo thiab siab ruaj khov thaum kub tsis tshua muaj kub. Ntawm ib sab tes, microwave hostenator tuaj yeem siv tau ua rau lub teeb liab actuarenters, thiab ntawm qhov tod tes, millimeter nthwv hluav taws xob muaj peev xwm siv tau los ua cua sov so. MM NTUJ Hostenator tuaj yeem siv rau hauv cov liaj teb xws li kev sib sib zog nqus, tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv cov kev sim qis thiab wiryconductor.

Lub hom phiaj:

1. Cov teeb liab attenuation: cryogenic taag attenuics yog siv los ua kom yog muaj zog ntawm RF thiab microwave cim hauv qhov chaw kub tsawg. Qhov no yog qhov tseem ceeb rau kev tiv thaiv rhiab cov khoom siv thiab cov cim teeb liab.
2. Cov suab nrov tswj: los ntawm kev tswj hwm lub teeb liab, lub suab nrov thiab cuam tshuam hauv lub kaw lus tuaj yeem txo, yog li kev txhim kho lub teeb liab-rau-suab nrov piv (SNR) ntawm lub teeb liab.
3. Kev txuam nrog: Cryogenic taag attenenators tuaj yeem siv los phim cov impedance ntawm lub system, yog li txiav txim siab ua kom muaj kev cuam tshuam thiab txhim kho kev ua haujlwm.

Daim Ntawv Thov:

1 Cov kev sim no feem ntau koom nrog kev kawm txog superconductors, quantum xam thiab lwm yam tsawg-kub tshwm sim.
2. Superconductor Kev Tshawb Fawb: Hauv Superconductor Tshawb Nrhiav, Cryogenic taag attenters thiab microwave qhia kom kawm cov khoom thiab kev coj cwj pwm ntawm superconductors.
3. Quantum xam: Hauv Quantum suav txog, CryogenicA taag hostrenator yog siv los tswj lub zog thiab kev sib cuam tshuam ntawm Quantum (qubits). Qhov no yog qhov tseem ceeb rau kev ua tiav high-precision quantum suav xam cov haujlwm.
4. Astronomy thiab Xov Tooj Cua Telescopes: Hauv cov xov tooj cua Astronomes, cov xov tooj cua ntaus xov tooj cua, RF ettrenters siv los kho lub zog ntawm cov cim npe celestial. Qhov no pab txhim kho qhov zoo thiab raug ntawm cov ntaub ntawv saib xyuas.
5. Cryogenic cov khoom siv hluav taws xob hauv hluav taws xob: hauv cov khoom siv hauv hluav taws xob tsawg, microwave hostuatator tau siv los tswj thiab kho teeb meem lub teeb meem kom ntseeg tau tias cov khoom siv ua haujlwm zoo.
Hauv ntej, cryogenic taag deluens actuareds tau siv dav nyob rau hauv ntau cov liaj teb xws li kev tshawb fawb cryogenic, quantum suav, astronomy, thiab cryogenic tshuab hluav taws xob. Lawv txhim kho kev ua haujlwm ntawm cov txheej txheem thiab kev ntseeg tau los ntawm cov teeb liab uas muaj zog thiab txo lub suab nrov.

Tsim nyogCov khoom siv ntau yam precision cryogenic tkas delenuatorstooj npog qhov ntau dc ~ 40ghz. Lub zog nruab nrab yog 2 watts. Cov edenels siv nyob rau hauv ntau cov ntawv thov uas yuav tsum tau txo lub zog hluav taws xob.
