Ƙaramin Ƙarfin Ƙarar Hayaniya Mai Ƙarfi

Masu ƙara sautin ƙara na Cryogenic (LNAs) na'urori ne na lantarki na musamman waɗanda aka ƙera don ƙara sigina masu rauni tare da ƙaramin ƙara, yayin da suke aiki a yanayin zafi mai ƙanƙanta (yawanci yanayin zafin helium na ruwa, 4K ko ƙasa da haka). Waɗannan amplifiers suna da mahimmanci a aikace-aikace inda amincin sigina da jin daɗinsu suka fi muhimmanci, kamar su kwamfuta mai ƙarfin lantarki, ilmin taurari na rediyo, da na'urorin lantarki masu ƙarfin lantarki. Ta hanyar aiki a yanayin zafi mai ƙarfi, LNAs suna samun ƙarancin adadin hayaniyar idan aka kwatanta da takwarorinsu na yanayin zafi na ɗakinsu, wanda hakan ke sa su zama dole a cikin tsarin kimiyya da fasaha mai inganci.

Siffofi:

1. Siffar Ƙarancin Hayaniya Mai Rauni: Rf cryogenic LNAs suna samun ƙimar hayaniyar ƙasa da kashi goma na decibel (dB), wanda ya fi kyau fiye da amplifiers na zafin ɗaki. Wannan ya faru ne saboda raguwar hayaniyar zafi a yanayin zafi mai zafi.
2. Babban Riba: Yana samar da babban faɗaɗa sigina (yawanci 20-40 dB ko fiye) don haɓaka sigina masu rauni ba tare da rage darajar sigina-zuwa-amo ba (SNR).
3. Faɗin Bandwidth: Yana tallafawa nau'ikan mita daban-daban, daga MHz kaɗan zuwa GHz da yawa, ya danganta da ƙira da aikace-aikacen.
4. Dacewar Cryogenic: Na'urorin ƙara sauti na microwave waɗanda aka tsara don aiki da inganci a yanayin zafi mai ƙarfi (misali, 4K, 1K, ko ma ƙasa da haka). An gina su ta amfani da kayan aiki da abubuwan da ke kula da halayensu na lantarki da na injiniya a ƙananan yanayin zafi.
5. Ƙarancin Amfani da Wutar Lantarki: An inganta shi don ƙarancin watsa wutar lantarki don guje wa dumama yanayin da ke haifar da hayaniya, wanda zai iya lalata tsarin sanyaya.
6. Tsarin da ba shi da nauyi kuma mai sauƙi: An ƙera shi don haɗawa cikin tsarin da ke haifar da hayaniya, inda sarari da nauyi galibi suna da iyaka.
7. Babban Layi: Yana kiyaye ingancin sigina koda a manyan matakan wutar lantarki, yana tabbatar da ingantaccen haɓakawa ba tare da murɗewa ba.

Aikace-aikace:

1. Kwamfutar Kwamfuta: Ana amfani da na'urorin ƙara sauti na milimita masu ƙarfi waɗanda ke aiki a cikin na'urorin sarrafa kwantum don ƙara ƙarfin siginar karantawa daga qubits, wanda ke ba da damar auna yanayin kwantum daidai. An haɗa su cikin na'urorin sanyaya na'urorin sanyaya don aiki a yanayin zafi na millikelvin.
2. Ilimin Taurari na Rediyo: Ana amfani da shi a cikin masu karɓar na'urorin hangen nesa na rediyo don ƙara wa sigina masu rauni daga abubuwan sama masu nisa, yana inganta saurin fahimta da kuma warware abubuwan da aka lura a sararin samaniya.
3. Na'urorin Lantarki Masu Sarrafa Wutar Lantarki: na'urorin ƙara ƙarfin hayaniya na mm waɗanda ake amfani da su a cikin da'irori masu sarrafa wutar lantarki da na'urori masu auna sigina don ƙara ƙarfin sigina yayin da ake kiyaye ƙarancin hayaniyar, tabbatar da ingantaccen sarrafa sigina da aunawa.
4. Gwaje-gwajen Ƙananan Zafin Jiki: Ana amfani da su a cikin saitunan bincike na cryogenic, kamar nazarin superconductivity, abubuwan da ke faruwa a cikin kwantum, ko gano abubuwa masu duhu, don ƙara yawan sigina masu rauni tare da ƙaramin hayaniya.
5. Hoton Likitanci: Ana amfani da shi a cikin tsarin daukar hoto na zamani kamar MRI (Magnetic Resonance Imaging) waɗanda ke aiki a yanayin zafi mai zafi don haɓaka ingancin sigina da ƙuduri.
6. Sadarwar Sararin Samaniya da Tauraron Dan Adam: Ana amfani da shi a cikin tsarin sanyaya iska na kayan aikin sararin samaniya don ƙara yawan sigina masu rauni daga sararin samaniya mai zurfi, yana inganta ingancin sadarwa da ingancin bayanai.
7. Kimiyyar Kwayoyin Halitta: Ana amfani da shi a cikin na'urorin gano ƙwayoyin cuta don gwaje-gwaje kamar gano neutrino ko binciken abubuwa masu duhu, inda ƙara yawan hayaniya yake da matuƙar muhimmanci.

Qualwaveyana samar da Amplifiers na Ƙarancin Hayaniya na Cryogenic daga DC zuwa 8GHz, kuma zafin hayaniyar na iya zama ƙasa da 10K.
