XHUMANA MANJE

I-Attenuator iyingxenye yokulawula umsebenzi wayo oyinhloko uwukunciphisa amandla esiginali adlula ku-attenuator. Ezisetshenziswa ezingokoqobo, izibambisi ze-RF zingase zisebenze ezindaweni ezihlukene zokushisa, okubangele izibambisi ezigxilile ze-lcryogenic. Sidizayine izinqamuleli zezindawo zokushisa eziphansi (-269~+125 degrees Celsius) ngokukhetha izinto zokusetshenziswa ezifanele kanye nokuthuthukisa izinga lobuchwepheshe.

I-Cryogenic fixed attenuators ine-conductivity enhle yokushisa kanye nokuzinza okuphezulu emazingeni okushisa aphansi kakhulu. Ngakolunye uhlangothi, i-microwave attenuator ingasetshenziswa njengezibambisi zesignali ze-amplitude, kanti ngakolunye uhlangothi, i-millimeter wave attenuator ingasetshenziswa njengamasinki okushisa ukuze kudluliselwe okubandayo. I-Mm wave attenuator ingasetshenziswa emikhakheni efana nokuhlola indawo ejulile, isayensi yezinkanyezi yomsakazo, i-quantum computing, nokuxhumana okungenantambo, ikakhulukazi ocwaningweni lwe-physics esezingeni eliphansi kanye nocwaningo lwe-superconductor.

Inhloso:

1. Ukuncipha Kwesiginali: Izibambisi ezigxilile ze-Cryogenic zisetshenziselwa ukunciphisa ngokunembile amandla amasiginali e-RF kanye ne-microwave endaweni yokushisa ephansi kakhulu. Lokhu kubalulekile ukuze kuvikelwe amathuluzi amukelayo azwelayo kanye nokulawula amazinga esignali.
2. Ukulawulwa Komsindo: Ngokunciphisa isignali, umsindo nokuphazamiseka ohlelweni kungancishiswa, ngaleyo ndlela kuthuthukiswe isilinganiso sesignali-kuya-noise (SNR) yesiginali.
3. I-Impedance Efanisayo: I-Cryogenic fixed attenuators ingasetshenziswa ukufanisa i-impedance yesistimu, ngaleyo ndlela kuncishiswe ukucabangela kanye namagagasi amile futhi kuthuthukise ukusebenza kwesistimu.

Isicelo:

1. Ukuhlolwa kwe-Cryogenic physics: Ezivivinyweni zefiziksi yezinga lokushisa eliphansi, ama-cryogenic fixed attenuators asetshenziselwa ukulawula nokulungisa ukuqina kwesignali. Lezi zivivinyo zivame ukubandakanya ukutadisha ama-superconductors, i-quantum computing nezinye izenzakalo ezisezingeni eliphansi lokushisa.
2. Ucwaningo lwe-Superconductor: Ocwaningweni lwe-superconductor, ama-cryogenic fixed attenuators asetshenziselwa ukubeka nokulawula amaza omsakazo namasignali ama-microwave ukuze kufundwe izici nokuziphatha kwama-superconductors.
3. I-Quantum Computing: Kuzinhlelo zekhompuyutha ze-quantum, i-cryogenic fixed attenuator isetshenziselwa ukulawula amandla esignali nokusebenzisana phakathi kwamabhithi e-quantum (qubits). Lokhu kubalulekile ukuze kuzuzwe imisebenzi yekhompyutha ye-quantum enembe kakhulu.
4. I-Astronomy kanye ne-Radio Telescopes: Ezinhlelweni ze-astronomy kanye ne-radio telescope, ama-RF attenuators asetshenziselwa ukulungisa amandla amasignali asemkhathini awamukelwe. Lokhu kusiza ukuthuthukisa ikhwalithi nokunemba kwedatha yokubuka.
5. I-Cryogenic Electronic Equipment: Emishinini ye-elekthronikhi esezingeni eliphansi, i-microwave attenuator isetshenziselwa ukulawula nokulungisa amandla esignali ukuze kuqinisekiswe ukusebenza okuvamile 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 kagesi ye-cryogenic. Bathuthukisa ukusebenza kwesistimu nokuthembeka ngokulawula ngokunembile amandla esignali nokunciphisa umsindo.

Qualwaveihlinzeka ngezibambisi ezithile ezinembayo eziqinile ze-cryogenic ezimboza ibanga lemvamisa ye-DC~40GHz. Amandla amaphakathi ama-watts angu-2. Ama-attenuators asetshenziswa ezinhlelweni eziningi lapho kudingeka khona ukunciphisa amandla.
