Attenuator waa qayb ka mid ah kantaroolka oo shaqadiisa ugu weyni ay tahay in la yareeyo xoogga calaamada ee dhexmarta attenuator-ka. Codsiyada wax ku oolka ah, attenuators RF ayaa laga yaabaa inay ka shaqeeyaan jawi heerkuleed oo kala duwan, taasoo keenaysa attenuators go'an lcryogenic. Waxaan u qaabeynay attenuators jawiyada heerkulka hooseeya (-269 ~ + 125 darajo Celsius) anagoo dooranayna alaabta ceeriin ee ku haboon iyo hagaajinta heerka farsamada.

Attenuators go'an ee loo yaqaan 'Cryogenic attenuators' waxay leeyihiin kuleyl wanaagsan iyo xasillooni heerkul aad u hooseeya. Dhinaca kale, attenuator microwave waxaa loo isticmaali karaa sida attenuators amplitude signal, iyo dhinaca kale, attenuator mowjadda millimeter waxaa loo isticmaali karaa sidii weel kulaylka wareejinta qabow. Mm wave attenuator waxaa loo isticmaali karaa meelaha ay ka midka yihiin sahaminta meel qoto dheer, xiddigiska raadiyaha, xisaabinta quantum-ka, iyo isgaarsiinta wireless-ka, gaar ahaan tijaabooyinka fiisigiska heerkulka hooseeya iyo cilmi baarista sare.

Ujeedada:

1. Attenuation Signal: Attenuators go'an ee Cryogenic waxaa loo isticmaalaa in si sax ah loo yareeyo xoogga calaamadaha RF iyo microwave ee jawiga heerkulka aadka u hooseeya. Tani waxay muhiim u tahay ilaalinta qalabka xasaasiga ah ee helitaanka iyo xakamaynta heerarka calaamadaha.
2. Xakamaynta qaylada: Iyadoo la yareynayo calaamada, buuqa iyo faragelinta nidaamka waa la dhimi karaa, taas oo hagaajinaysa saamiga signal-ilaa-sanqada (SNR) ee calaamadda.
3. Matching Impedance: Attenuators go'an ee Cryogenic waxaa loo isticmaali karaa si loo waafajiyo caqabada nidaamka, si loo yareeyo milicsiga iyo hirarka taagan iyo hagaajinta waxqabadka nidaamka.

Codsiga:

1. Tijaabada Fiisigiska Cryogenic: Tijaabada fiisigiska heerkulka hooseeya, attenuators go'an cryogenic ayaa loo isticmaalaa si loo xakameeyo loona hagaajiyo xoojinta calaamadaha. Tijaabooyinkani waxay inta badan ku lug leeyihiin daraasadda kontaroolada sare, xisaabinta quantum-ka iyo dhacdooyinka kale ee heerkulka hooseeya.
2. Cilmi-baarista Superconductor: Cilmi-baarista superconductor, attenuators go'an cryogenic waxaa loo isticmaalaa in lagu xakameeyo inta jeer ee raadiyaha iyo calaamadaha microwave-ka si loo barto sifooyinka iyo habdhaqanka superconductors.
3. Xisaabinta Quantum: Nidaamyada xisaabinta quantum-ka, attenuator go'an cryogenic ayaa loo isticmaalaa si loo xakameeyo xoogga signalada iyo isdhexgalka ka dhexeeya quantum bits (qubits). Tani waxay muhiim u tahay gaaritaanka hawlgallada xisaabinta tirada saxda ah ee saxda ah.
4. Astronomy iyo Telescopes Raadiyaha: Xiddigga xiddigiska iyo nidaamyada telescope radio, attenuators RF ayaa loo adeegsadaa si loo hagaajiyo xoogga calaamadaha samada ee la helay. Tani waxay gacan ka geysaneysaa hagaajinta tayada iyo saxnaanta xogta indha-indheynta.
5. Qalabka Elektrooniga ah ee Cryogenic: Qalabka elektiroonigga ah ee heerkulka hooseeya, microwave attenuator waxaa loo isticmaalaa in lagu xakameeyo oo lagu hagaajiyo xoogga calaamadaha si loo hubiyo hawlgalka caadiga ah iyo waxqabadka sare ee qalabka.
Marka la soo koobo, attenuators go'an cryogenic ayaa si weyn loogu isticmaalaa dhinacyo badan sida tijaabooyinka fiisigiska cryogenic, cilmi baarista superconductor, xisaabinta tirada, xiddigiska, iyo qalabka elektiroonigga ah ee cryogenic. Waxay wanaajiyaan waxqabadka nidaamka iyo isku halaynta iyagoo si sax ah u xakameynaya xoogga calaamadaha oo yareynaya buuqa.

Qualwavesahayda kala duwan ee saxda ah ee saxda ah ee cryogenic attenuators go'an daboolo inta jeer ee DC ~ 40GHz. Awoodda celceliska waa 2 watts. Attenuators waxaa loo isticmaalaa codsiyo badan oo loo baahan yahay dhimista awoodda.
