Cov Amplifiers Uas Tsis Muaj Suab Nrov Cryogenic

Cov Amplifiers Noise Low Noise (LNAs) yog cov khoom siv hluav taws xob tshwj xeeb uas tsim los ua kom cov teeb liab tsis muaj zog nrog lub suab nrov tsawg kawg nkaus, thaum ua haujlwm ntawm qhov kub qis heev (feem ntau yog cov kua helium kub, 4K lossis qis dua). Cov amplifiers no yog qhov tseem ceeb hauv cov ntawv thov uas qhov kev ncaj ncees ntawm cov teeb liab thiab kev nkag siab yog qhov tseem ceeb, xws li quantumcomputing, xov tooj cua astronomy, thiab superconducting electronics. Los ntawm kev ua haujlwm ntawm qhov kub cryogenic, LNAs ua tiav cov suab nrov qis dua piv rau lawv cov chav tsev-kub counterparts, ua rau lawv tsis tseem ceeb hauv cov txheej txheem kev tshawb fawb thiab thev naus laus zis siab.

Nta:

1. Daim Duab Suab Nrov Tsawg Kawg Nkaus: Rf cryogenic LNAs ua tiav cov suab nrov qis li ob peb feem kaum ntawm decibel (dB), uas zoo dua li cov amplifiers kub hauv chav. Qhov no yog vim muaj kev txo qis ntawm lub suab nrov thermal ntawm qhov kub cryogenic.
2. Kev Nce Siab: Muab kev ua kom lub teeb liab loj dua (feem ntau yog 20-40 dB lossis ntau dua) los txhawb cov teeb liab tsis muaj zog yam tsis ua rau qhov sib piv ntawm lub teeb liab thiab lub suab nrov (SNR) poob qis.
3. Bandwidth Dav: Txhawb nqa ntau yam zaus, txij li ob peb MHz mus rau ntau GHz, nyob ntawm tus qauv tsim thiab daim ntawv thov.
4. Kev Sib Tw Nrog Cryogenic: Cov amplifiers microwave cryogenic uas tsis muaj suab nrov uas tsim los ua haujlwm tau zoo ntawm qhov kub cryogenic (piv txwv li, 4K, 1K, lossis qis dua). Tsim los ntawm kev siv cov ntaub ntawv thiab cov khoom uas tswj lawv cov khoom siv hluav taws xob thiab kho tshuab ntawm qhov kub qis.
5. Kev Siv Hluav Taws Xob Tsawg: Zoo tshaj plaws rau kev siv hluav taws xob tsawg kawg nkaus kom tsis txhob muaj cua sov rau qhov chaw cryogenic, uas tuaj yeem ua rau lub kaw lus txias tsis ruaj khov.
6. Kev Tsim Qauv Me Me thiab Lub Teeb Meem: Tsim los rau kev koom ua ke rau hauv cov kab ke cryogenic, qhov twg qhov chaw thiab qhov hnyav feem ntau txwv.
7. High Linearity: Tswj cov teeb liab kom ruaj khov txawm tias nyob rau theem siab zog, kom ntseeg tau tias qhov amplification raug yam tsis muaj kev cuam tshuam.

Cov ntawv thov:

1. Kev Xam Xaj Quantum: Cov tshuab ua kom nrov nrov millimeter wave cryogenic siv rau hauv cov txheej txheem quantum superconducting los ua kom cov teeb liab nyeem tsis muaj zog los ntawm qubits, ua kom ntsuas tau qhov tseeb ntawm cov xwm txheej quantum. Koom ua ke rau hauv cov tub yees dilution kom ua haujlwm ntawm qhov kub millikelvin.
2. Kev Tshawb Fawb Txog Hnub Qub Hauv Xov Tooj Cua: Siv rau hauv cov khoom siv cryogenic ntawm cov xov tooj cua telescopes los ua kom cov teeb liab tsis meej los ntawm cov khoom nyob deb ntawm lub ntuj ceeb tsheej, txhim kho qhov rhiab heev thiab kev daws teeb meem ntawm kev soj ntsuam hnub qub.
3. Cov Khoom Siv Hluav Taws Xob Superconducting: mm nthwv dej cryogenic suab nrov qis amplifiers siv rau hauv superconducting circuits thiab sensors los ua kom cov teeb liab tsis muaj zog thaum tswj cov suab nrov qis, kom ntseeg tau tias cov teeb liab ua tiav thiab ntsuas tau raug.
4. Kev Sim Kub Qis: Siv rau hauv kev tshawb fawb cryogenic, xws li kev tshawb fawb txog superconductivity, quantum phenomena, lossis kev tshawb pom cov khoom tsaus nti, los ua kom cov teeb liab tsis muaj zog nrog suab nrov tsawg kawg nkaus.
5. Kev Siv Duab Kho Mob: Siv rau hauv cov tshuab siv duab siab heev xws li MRI (Magnetic Resonance Imaging) uas ua haujlwm ntawm qhov kub cryogenic los txhim kho qhov zoo thiab kev daws teeb meem ntawm lub teeb liab.
6. Kev Sib Txuas Lus Hauv Qhov Chaw Thiab Satellite: Siv rau hauv cov tshuab cua txias cryogenic ntawm cov cuab yeej siv hauv qhov chaw kom ua kom cov teeb liab tsis muaj zog los ntawm qhov chaw tob, txhim kho kev sib txuas lus zoo thiab cov ntaub ntawv zoo.
7. Kev Tshawb Fawb Txog Cov Khoom Me Me: Siv rau hauv cov khoom siv cryogenic rau kev sim xws li kev tshawb nrhiav neutrino lossis kev tshawb nrhiav cov khoom tsaus nti, qhov twg qhov kev ua kom nrov nrov tsawg heev yog qhov tseem ceeb.

Qualwavemuab cov Cryogenic Low Noise Amplifiers los ntawm DC mus rau 8GHz, thiab qhov kub ntawm lub suab nrov tuaj yeem qis txog 10K.
