O le Attenuator o se vaega faʻatonutonu o lana galuega autu o le faʻaitiitia o le malosi o le faailo e ui atu i le attenuator. I fa'atinoga fa'atino, e mafai ona fa'agaoioi le attenuators i si'osi'omaga eseese o le vevela, ma fa'atupuina ai attenuators tumau lcryogenic. Ua matou mamanuina attenuators mo siosiomaga maualalo vevela (-269 ~ + 125 tikeri Celsius) e ala i le filifilia o mea mataʻina talafeagai ma faʻaleleia le tulaga o tekinolosi.
Cryogenic attenuators tumau lelei conductivity vevela ma mautu maualuga i matua maualalo vevela. I le tasi itu, e mafai ona faʻaaogaina e fai ma faʻailoga faʻapipiʻi amplitude, ma i le isi itu, e mafai ona faʻaaogaina e pei o le vevela mo le malulu malulu. E mafai ona fa'aoga i matā'upu e pei o su'esu'ega va'ava'a loloto, su'esu'ega o le leitio, su'esu'ega quantum, ma feso'ota'iga uaealesi, aemaise i su'esu'ega o le fisiki maualalo ma su'esu'ega superconductor.
1. Fa'ailo Fa'ailo: O lo'o fa'aaogaina fa'amaumau fa'amaumau maualalo le vevela e fa'ato'a sa'o ai le malosi o fa'ailoga RF ma microwave i si'osi'omaga e matua'i maualalo le vevela. E taua tele lenei mea mo le puipuia o masini maaleale taliaina ma le puleaina o faʻailoga.
2. Pulea le Pisa: E ala i le faʻaitiitia o le faʻailoga, o le pisa ma le faʻalavelave i le faiga e mafai ona faʻaitiitia, ma faʻaleleia atili ai le faʻasologa o le faʻailoga (SNR) o le faailo.
3. Matching Impedance: E mafai ona faʻaogaina attenuators faʻamaumau maualalo e faʻafetaui le faʻalavelave o le faiga, ma faʻaitiitia ai mafaufauga ma galu tu ma faʻaleleia le faʻatinoga o faiga.
1. Fa'ata'ita'iga o le fisiki Cryogenic: I fa'ata'ita'iga o le fisiki maualalo, e fa'aaogaina attenuators fa'amaumau maualalo e pulea ma fetu'una'i le malosi o fa'ailo. O nei faʻataʻitaʻiga e masani ona aofia ai suʻesuʻega o superconductors, quantum computing ma isi faʻalavelave maualalo-vevela.
2. Su'esu'ega Superconductor: I su'esu'ega superconductor, o lo'o fa'aogaina cryogenic fa'amautu attenuators e fa'amautu ma fa'atonutonu alaleo alaleo ma microwave fa'ailoga e su'esu'e ai meatotino ma amioga a superconductor.
3. Quantum Computing: I le quantum computing system, cryogenically fixed attenuators e faʻaogaina e faʻatonutonu ai le malosi o faʻailoga ma fegalegaleaiga i le va o quantum bits (qubits). E taua tele lenei mea mo le ausiaina o galuega fa'akomepiuta sa'o maualuga.
4. Astronomy ma Leitio Telescopes: I su'esu'ega fetū ma leitio fa'aata, o lo'o fa'aogaina cryogenic attenuators e fa'afetaui ai le malosi o fa'ailo fa'aselesitila maua. E fesoasoani lea e fa'aleleia atili ai le lelei ma le sa'o o fa'amatalaga mata'ituina.
5. Cryogenic Electronic Equipment: I totonu o masini eletise eletise maualalo, o loʻo faʻaaogaina attenuators faʻamautu maualalo e pulea ma fetuutuunai le malosi faʻailoga e faʻamautinoa ai le faʻaogaina masani ma le maualuga o le faʻatinoga o meafaigaluega.
I se faapuupuuga, o le cryogenic fixed attenuators o loʻo faʻaaogaina lautele i le tele o matāʻupu e pei o le cryogenic physics faʻataʻitaʻiga, suʻesuʻega superconductor, quantum computing, astronomy, ma masini eletise cryogenic.. Latou te faʻaleleia le faʻatinoga o le faiga ma le faʻamaoni e ala i le pulea saʻo o le malosi faʻailoga ma faʻaitiitia le pisa.
Qualwavetu'uina atu i luga o le sa'o maualuga cryogenic attenuators fa'amautu e ufiufi le va'ava'a DC ~ 40GHz. Ole malosi ole malosi ole 2 watts. O attenuators e faʻaaogaina i le tele o talosaga e manaʻomia ai le faʻaitiitia o le mana.
