Iimbonakalo:
- I-VSWR ephantsi
- I-Attenuation Flatness ephezulu
I-Attenuator licandelo lokulawula umsebenzi walo ophambili kukunciphisa amandla omqondiso odlula kwi-attenuator. Kwizicelo ezisebenzayo, i-attenuators inokusebenza kwiimeko ezahlukeneyo zobushushu, ibangele i-lcryogenic fixed attenuators. 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 obushushu aphantsi kakhulu. Ngakolunye uhlangothi, zinokusetyenziswa njenge-attenuators ye-amplitude yesiginali, kwaye kwelinye icala, zinokusetyenziswa njengeendawo zokutshisa ubushushu bokudlulisa okubandayo. Ingasetyenziselwa kwiinkalo ezifana nokuhlola indawo enzulu, i-astronomy yerediyo, i-quantum computing, kunye nonxibelelwano olungenacingo, ngakumbi kwiimvavanyo ze-physics eziphantsi kunye nophando lwe-superconductor.
1. UkuNcitshiswa koMqondiso: Izithinteli zobushushu obuphantsi ezisisigxina zisetyenziselwa ukunciphisa ngokuchanekileyo amandla e-RF kunye neesignali ze-microwave kwiindawo eziphantsi kakhulu zobushushu.

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-attenuators ephantsi yokushisa ephantsi ingasetyenziselwa ukuhambelana nokuphazamiseka kwenkqubo, ngokunciphisa izibonakaliso kunye namaza okuma kunye nokuphucula ukusebenza kwenkqubo.
1. Umfuniselo wefiziksi yeCryogenic: Kwimifuniselo yefiziksi yobushushu obuphantsi, i-low-temperature fixed attenuators isetyenziselwa ukulawula nokulungelelanisa ubungakanani 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-cryogenically fixed attenuators isetyenziselwa ukulawula amandla omqondiso kunye nokusebenzisana phakathi kwe-quantum bits (qubits). Oku kubalulekile ekufezekiseni ukusebenza kwe-quantum computing echanekileyo ephezulu.
4. I-Astronomy kunye neRadio Telescopes: Kwi-astronomy kunye ne-radio telescope systems, i-cryogenic fixed attenuators isetyenziselwa ukunyenyisa amandla emiqondiso yesibhakabhaka efunyenweyo. Oku kunceda ukuphucula umgangatho kunye nokuchaneka kwedatha yokujonga.
5. Izixhobo ze-elektroniki ze-Cryogenic: Kwizixhobo ze-elektroniki ezisezantsi, i-low-temperature fixed attenuators isetyenziselwa ukulawula nokulungelelanisa amandla omqondiso ukuqinisekisa ukusebenza okuqhelekileyo kunye nokusebenza okuphezulu kwezixhobo.
Ngamafutshane, i-cryogenic fixed attenuators isetyenziswa ngokubanzi kwiinkalo ezininzi ezinje nge-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.
