    I-Attenuator licandelo lokulawula umsebenzi walo ophambili kukunciphisa amandla omqondiso odlula kwi-attenuator. Kwizinto ezisebenzayo, izithinteli zeRF zinokusebenza kwiimeko ezahlukeneyo zobushushu, nto leyo ekhokelela kwizithinteli ezisisigxina ze-lcryogenic. Siye sayila i-attenuators yeendawo zokushisa eziphantsi (-269 ~ + 125 degrees Celsius) ngokukhetha izixhobo ezifanelekileyo kunye nokuphucula umgangatho wobugcisa.

    I-Cryogenic fixed attenuators inokuqhuba kakuhle kwe-thermal kunye nokuzinza okuphezulu kumaqondo aphantsi kakhulu. Kwelinye icala, i-microwave attenuator inokusetyenziswa njengezithinteli zomqondiso weamplitude, kwaye kwelinye icala, i-millimeter wave attenuator inokusetyenziswa njengamatsinki obushushu ukuhambisa okubandayo. I-Mm wave attenuator ingasetyenziswa kwimimandla efana nophononongo olunzulu lwendawo, iastronomy yerediyo, i-quantum computing, kunye nonxibelelwano olungenazingcingo, ngakumbi kuvavanyo lwefiziksi yobushushu obuphantsi kunye nophando lwesuperconductor.

    Injongo:

    1. Ukuqwalaselwa koMqondiso: Izithinteli ezisisigxina zeCryogenic zisetyenziselwa ukunciphisa ngokuchanekileyo amandla e-RF kunye neesignali ze-microwave kwiindawo eziphantsi kakhulu zobushushu. Oku kubalulekile ekukhuseleni izixhobo zokwamkela ezinovakalelo kunye nokulawula amanqanaba ophawu.
    2. Ukulawulwa kwengxolo: Ngokunciphisa umqondiso, ingxolo kunye nokuphazamiseka kwinkqubo kunokuncitshiswa, ngaloo ndlela kuphuculwe i-signal-to-noise ratio (SNR) yesiginali.
    3. I-Impedance ehambelanayo: I-Cryogenic attenuators esisigxina ingasetyenziselwa ukufanisa i-impedance yenkqubo, ngokunciphisa izibonakaliso kunye namaza okuma kunye nokuphucula ukusebenza kwenkqubo.

    Isicelo:

    1. Umfuniselo wefiziksi yeCryogenic: Kwimifuniselo yefiziksi yobushushu obuphantsi, i-cryogenic fixed attenuators isetyenziselwa ukulawula nokulungelelanisa ubunzulu bomqondiso. Olu vavanyo luhlala lubandakanya uphononongo lwee-superconductors, i-quantum computing kunye nezinye izinto eziphantsi kobushushu.
    2. Uphando lwe-Superconductor: Kuphando lwe-superconductor, i-cryogenic fixed attenuators isetyenziselwa ukumisela kunye nokulawula i-radio frequency kunye neempawu ze-microwave ukufunda iipropati kunye nokuziphatha kwee-superconductors.
    3. I-Quantum Computing: Kwiinkqubo ze-quantum computing, i-cryogenic fixed attenuator isetyenziselwa ukulawula amandla omqondiso kunye nokusebenzisana phakathi kwe-quantum bits (qubits). Oku kubalulekile ekufezekiseni ukusebenza kwe-quantum computing echanekileyo ephezulu.
    4. I-Astronomy kunye neeteleskopu zeRadio: Kwi-astronomy kunye ne-radio telescope systems, ii-RF attenuators zisetyenziselwa ukunyenyisa amandla emiqondiso yesibhakabhaka efunyenweyo. Oku kunceda ukuphucula umgangatho kunye nokuchaneka kwedatha yokujonga.
    5. Izixhobo ze-elektroniki ze-Cryogenic: Kwizixhobo ze-elektroniki ezisezantsi, i-microwave attenuator isetyenziselwa ukulawula nokulungelelanisa amandla omqondiso ukuqinisekisa ukusebenza okuqhelekileyo kunye nokusebenza okuphezulu kwezixhobo.
    Ngamafutshane, i-cryogenic fixed attenuators isetyenziswa ngokubanzi kwiinkalo ezininzi ezifana ne-cryogenic physics experiments, uphando lwe-superconductor, i-quantum computing, i-astronomy, kunye nezixhobo ze-elektroniki ze-cryogenic. Baphucula ukusebenza kwenkqubo kunye nokuthembeka ngokulawula ngokuchanekileyo amandla omqondiso kunye nokunciphisa ingxolo.

    Qualwaveibonelela ngeendlela ezahlukeneyo zokuchaneka okuphezulu kwe-cryogenic attenuators ezisisigxina zigubungela uluhlu lwamaza e-DC ~ 40GHz. Amandla aphakathi ziiwatts ezi-2. I-attenuators isetyenziswa kwizicelo ezininzi apho ukuncitshiswa kwamandla kuyadingeka.
