Cryogenic Low Noise Amplifiers

Cryogenic Low Noise Amplifiers (LNAs) sune na'urorin lantarki na musamman waɗanda aka tsara don haɓaka sigina mara ƙarfi tare da ƙaramar ƙara ƙaranci, yayin aiki a matsanancin yanayin zafi (yawanci yanayin yanayin helium na ruwa, 4K ko ƙasa). Waɗannan amplifiers suna da mahimmanci a aikace-aikace inda amincin sigina da azanci ke da mahimmanci, kamar ƙidayar ƙididdigewa, ilimin taurari na rediyo, da na'urorin lantarki masu ƙarfi. Ta hanyar aiki a yanayin zafi na cryogenic, LNAs suna samun ƙarancin ƙarar amo sosai idan aka kwatanta da takwarorinsu na zafin daki, yana mai da su maƙasudi a cikin ingantattun tsarin kimiyya da fasaha.

Siffofin:

Hoto na Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarfafa: Rf cryogenic LNAs sun cimma alkaluman amo a matsayin ƙasa da kaɗan daga cikin goma na decibel (dB), wanda ya fi na'urorin haɓaka zafin ɗaki. Wannan shi ne saboda raguwar amo na thermal a yanayin zafi na cryogenic.
2. Babban Gain: Yana ba da haɓakar siginar sigina (yawanci 20-40 dB ko fiye) don haɓaka sigina masu rauni ba tare da lalata siginar sigina-zuwa-amo (SNR).
3. Wide Bandwidth: Yana goyan bayan mitoci masu yawa, daga ƴan MHz zuwa GHz da yawa, dangane da ƙira da aikace-aikace.
4. Cryogenic Compatibility: Microwave cryogenic low amo amplifiers tsara don aiki da dogara a cryogenic yanayin zafi (misali, 4K, 1K, ko ma m). Gina ta amfani da kayan aiki da abubuwan haɗin gwiwa waɗanda ke kula da kaddarorin lantarki da na injina a ƙananan yanayin zafi.
5. Karancin yawan iko: ingantawa don ƙarancin ƙarfin wutar lantarki don guje wa dumama yanayin muryar ruwa, wanda zai lalata tsarin sanyaya.

7. High Linearity: Yana kiyaye siginar siginar har ma a manyan matakan shigar da wutar lantarki, yana tabbatar da daidaito ba tare da murdiya ba.

Aikace-aikace:

1. Quimtum Haɗe cikin injin daskarewa don aiki a yanayin zafin millikelvin.
2. Tauraron Taurari na Rediyo: An yi aiki a cikin masu karɓar na'urar hangen nesa na rediyo don haɓaka sigina marasa ƙarfi daga abubuwan sararin samaniya mai nisa, haɓaka azanci da ƙuduri na abubuwan kallon taurari.
3. Superconducting Electronics: mm wave cryogenic low amo amplifiers amfani a superconducting circuits da na'urori masu auna sigina don ƙara rauni sigina yayin da rike low amo matakan, tabbatar da daidai siginar sarrafa da kuma auna.
4. Gwajin zazzabi mai yawa: amfani a cikin sethoset na bincike na bincike, kamar nazarin supercontuctionity, ko ganowa na zahiri, don fadada sigari na zamani, don fadada karfi da alama tare da amo.
5. Hoto na Likita: An yi amfani da shi a cikin tsarin zane-zane na ci gaba kamar MRI (Magnetic Resonance Imaging) wanda ke aiki a yanayin zafi na cryogenic don haɓaka ingancin sigina da ƙuduri.
6. Sarari da Sadarwar Tauraron Dan Adam: An yi amfani da shi a cikin tsarin kwantar da hankali na cryogenic na kayan aikin sararin samaniya don haɓaka sigina masu rauni daga sararin samaniya mai zurfi, inganta ingantaccen sadarwa da ingancin bayanai.
7. Barbashi Physics: Aiki a cikin masu gano cryogenic don gwaje-gwaje irin su gano neutrino ko binciken al'amuran duhu, inda haɓakar ƙarar ƙarar ƙarar ƙarar murya ke da mahimmanci.

Qualwaveyana samar da Cryogenic Low Noise Amplifiers daga DC zuwa 8GHz, kuma zafin amo na iya zama ƙasa da 10K.
