XHUMANA MANJE

I-Attenuator iyisakhi sokulawula esinomsebenzi oyinhloko ukunciphisa amandla esignali adlula ku-attenuator. Ezisetshenzisweni ezisebenzayo, ama-RF attenuator angasebenza ezindaweni ezahlukene zokushisa, okubangela ama-lcryogenic fixed attenuator. Siklame ama-attenuator ezindaweni eziphansi zokushisa (-269~+125 degrees Celsius) ngokukhetha izinto zokusetshenziswa ezifanele nokuthuthukisa izinga lobuchwepheshe.

Ama-attenuator aqinile e-cryogenic anomoya omuhle wokushisa kanye nokuqina okuphezulu emazingeni okushisa aphansi kakhulu. Ngakolunye uhlangothi, i-attenuator ye-microwave ingasetshenziswa njenge-attenuator ye-signal amplitude, kanti ngakolunye uhlangothi, i-attenuator yamagagasi e-millimeter ingasetshenziswa njengezinki zokushisa zokudlulisa okubandayo. I-attenuator yamagagasi e-Mm ingasetshenziswa emikhakheni efana nokuhlola isikhala okujulile, i-radio astronomy, i-quantum computing, kanye nokuxhumana okungenantambo, ikakhulukazi ekuhlolweni kwe-physics yokushisa okuphansi kanye nocwaningo lwe-superconductor.

Inhloso:

1. Ukuncishiswa Kwesignali: Ama-attenuator aqinile e-cryogenic asetshenziselwa ukunciphisa ngokunembile amandla esignali ye-RF kanye ne-microwave ezindaweni eziphansi kakhulu zokushisa. Lokhu kubalulekile ekuvikeleni imishini yokwamukela ebucayi kanye namazinga okulawula amasignali.
2. Ukulawulwa Komsindo: Ngokunciphisa isignali, umsindo kanye nokuphazamiseka ohlelweni kungancishiswa, ngaleyo ndlela kuthuthukiswe isilinganiso sesignali kuya komsindo (SNR) sesignali.
3. Ukufanisa Impedance: Ama-attenuator aqinile e-Cryogenic angasetshenziswa ukufanisa i-impedance yesistimu, ngaleyo ndlela anciphise ukubonakaliswa namagagasi amile futhi athuthukise ukusebenza kwesistimu.

Isicelo:

1. Ukuhlolwa kwe-Cryogenic physics: Ekuhlolweni kwe-physics okuphansi kwezinga lokushisa, ama-attenuator aqinile e-cryogenic asetshenziswa ukulawula nokulungisa ukuqina kwesiginali. Lokhu kuhlolwa kuvame ukuhilela ukutadisha ama-superconductor, i-quantum computing kanye nezinye izimo eziphansi kwezinga lokushisa.
2. Ucwaningo lwe-Superconductor: Ocwaningweni lwe-superconductor, ama-cryogenic fixed attenuators asetshenziselwa ukulungisa nokulawula imvamisa yomsakazo kanye namasignali e-microwave ukuze kufundwe izakhiwo kanye nokuziphatha kwama-superconductors.
3. I-Quantum Computing: Ezinhlelweni zokubala ze-quantum, i-cryogenic fixed attenuator isetshenziswa ukulawula amandla esignali kanye nokusebenzisana phakathi kwama-quantum bits (qubits). Lokhu kubalulekile ekufezeni imisebenzi yokubala ye-quantum enembile kakhulu.
4. Ama-Astronomy kanye nama-Radio Telescope: Ezinhlelweni ze-astronomy kanye ne-radio telescope, ama-RF attenuator asetshenziswa ukulungisa amandla ezibonakaliso zasezulwini ezitholiwe. Lokhu kusiza ukuthuthukisa ikhwalithi kanye nokunemba kwedatha yokubuka.
5. Imishini Ye-elekthronikhi Ene-Cryogenic: Emishinini ye-elekthronikhi enezinga lokushisa eliphansi, i-microwave attenuator isetshenziswa ukulawula nokulungisa amandla esignali ukuqinisekisa ukusebenza okuvamile kanye nokusebenza okuphezulu kwemishini.
Ngamafuphi, ama-cryogenic fixed attenuators asetshenziswa kabanzi emikhakheni eminingi efana nokuhlolwa kwe-cryogenic physics, ucwaningo lwe-superconductor, i-quantum computing, i-astronomy, kanye nemishini ye-cryogenic electronic. Athuthukisa ukusebenza kwesistimu kanye nokuthembeka ngokulawula ngokunembile amandla esignali nokunciphisa umsindo.

I-Qualwaveinikeza ama-attenuator ahlukahlukene aqinile e-cryogenic aqondile amboza ububanzi bemvamisa DC ~ 40GHz. Amandla ajwayelekile angama-watts ama-2. Ama-attenuator asetshenziswa ezindaweni eziningi lapho kudingeka khona ukunciphisa amandla.
