Ama-Amplifiers Omsindo Ophansi we-Cryogenic

Ama-Cryogenic Low Noise Amplifier (ama-LNA) angamadivayisi akhethekile kagesi aklanyelwe ukukhulisa izimpawu ezibuthakathaka ngomsindo omncane owengeziwe, ngenkathi esebenza emazingeni okushisa aphansi kakhulu (ngokuvamile amazinga okushisa e-helium acwebezelayo, angu-4K noma ngaphansi). Lawa ma-amplifier abaluleke kakhulu ekusetshenzisweni lapho ubuqotho besignali kanye nokuzwela kubaluleke kakhulu, njenge-quantumcomputing, i-radio astronomy, kanye ne-superconducting electronics. Ngokusebenza emazingeni okushisa e-cryogenic, ama-LNA athola izibalo zomsindo eziphansi kakhulu uma kuqhathaniswa nezinye zazo ezisezingeni lokushisa legumbi, okwenza abaluleke kakhulu ezinhlelweni zesayensi nezobuchwepheshe ezinembile kakhulu.

Izici:

1. Isibalo Somsindo Ophansi Kakhulu: Ama-LNA e-Rf cryogenic athola izibalo zomsindo eziphansi njengezingxenye ezimbalwa zeshumi ze-decibel (dB), okungcono kakhulu kunezikhulisi zokushisa kwegumbi. Lokhu kungenxa yokwehla komsindo wokushisa emazingeni okushisa e-cryogenic.
2. Inzuzo Ephakeme: Ihlinzeka ngokukhulisa isignali ephezulu (ngokuvamile 20-40 dB noma ngaphezulu) ukukhulisa isignali ebuthakathaka ngaphandle kokwehlisa isilinganiso sesignali-kuya-kumsindo (i-SNR).
3. I-Bandwidth Ebanzi: Isekela ububanzi obukhulu bemvamisa, kusukela ku-MHz embalwa kuya ku-GHz eziningana, kuye ngomklamo kanye nokusetshenziswa.
4. Ukuhambisana kwe-Cryogenic: Ama-amplifier omsindo ophansi we-microwave cryogenic aklanyelwe ukusebenza ngokuthembekile emazingeni okushisa e-cryogenic (isb., 4K, 1K, noma ngisho nangaphansi). Akhiwe kusetshenziswa izinto nezinto ezigcina izakhiwo zawo zikagesi nezomshini emazingeni okushisa aphansi.
5. Ukusetshenziswa Kwamandla Aphansi: Kwenzelwe ukushabalalisa amandla amancane ukuze kugwenywe ukushisa indawo engcolile, okungaphazamisa uhlelo lokupholisa.
6. Umklamo Omncane Nolula: Wenzelwe ukuhlanganiswa nezinhlelo ze-cryogenic, lapho isikhala nesisindo kuvame ukulinganiselwa.
7. Ukulingana Okuphezulu: Igcina ubuqotho besiginali ngisho nasemazingeni aphezulu wamandla okufaka, iqinisekisa ukukhuliswa okunembile ngaphandle kokuphazamiseka.

Izicelo:

1. I-Quantum Computing: Ama-amplifiers omsindo ophansi we-Millimeter wave cryogenic asetshenziswa kuma-superconducting quantum processors ukukhulisa izimpawu zokufunda ezibuthakathaka ezivela kuma-qubits, okuvumela ukulinganiswa okunembile kwezimo ze-quantum. Ahlanganiswe nama-dilutionrefrigerators ukuze asebenze emazingeni okushisa e-millikelvin.
2. I-Radio Astronomy: Isetshenziswa kuma-cryogenic receivers ama-radio telescopes ukuze ikhulise izimpawu ezibuthakathaka ezivela ezintweni zasezulwini ezikude, ithuthukise ukuzwela kanye nokuxazululwa kokubhekwa kwezinkanyezi.
3. I-Superconducting Electronics: ama-mm wave cryogenic low noise amplifiers asetshenziswa kumasekethe e-superconducting kanye nezinzwa ukukhulisa izimpawu ezibuthakathaka ngenkathi kugcinwa amazinga omsindo aphansi, okuqinisekisa ukucutshungulwa kwesignali okunembile kanye nokulinganiswa kwayo.
4. Ukuhlolwa Kokushisa Okuphansi: Kusetshenziswa ezisekelweni zocwaningo lwe-cryogenic, njengezifundo ze-superconductivity, i-quantum phenomena, noma ukutholwa kwezinto ezimnyama, ukuze kukhuliswe izimpawu ezibuthakathaka ngomsindo omncane.
5. Ukuthwebula Izithombe Kwezokwelapha: Kusetshenziswa ezinhlelweni zokuthwebula izithombe ezithuthukisiwe njenge-MRI (Magnetic Resonance Imaging) ezisebenza emazingeni okushisa acwebezelayo ukuze kuthuthukiswe ikhwalithi yesignali kanye nesisombululo.
6. Ukuxhumana Kwesikhala Nesathelayithi: Kusetshenziswa ezinhlelweni zokupholisa zemishini esekelwe esikhaleni ukukhulisa izimpawu ezibuthakathaka ezivela esikhaleni esijulile, ukuthuthukisa ukusebenza kahle kokuxhumana kanye nekhwalithi yedatha.
7. I-Particle Physics: Isetshenziswa kuma-cryogenic detectors okuhlola okufana nokutholwa kwe-neutrino noma ukusesha izinto ezimnyama, lapho ukukhulisa umsindo ophansi kakhulu kubaluleke kakhulu.

I-Qualwaveinikeza ama-Cryogenic Low Noise Amplifiers kusukela ku-DC kuya ku-8GHz, futhi izinga lokushisa lomsindo lingaba ngaphansi kuka-10K.
