Cryogenic Yoroheje Urusaku rwinshi

Cryogenic Low Noise Amplifiers (LNAs) ni ibikoresho bya elegitoroniki byabugenewe bigamije kongera ibimenyetso bidakomeye hamwe n’urusaku ruke rwiyongereye, mu gihe rukora ku bushyuhe buke cyane (ubusanzwe ubushyuhe bwa helium, 4K cyangwa munsi). Izi amplifier ningirakamaro mubikorwa aho ibimenyetso byerekana ubunyangamugayo hamwe nubukangurambaga nibyingenzi, nka quantumcomputing, radio astronomie, na electronique superconducting. Mugukora mubushyuhe bwa kirogenike, LNAs igera kumubare muto wurusaku ugereranije nubushyuhe bwicyumba cyabo, bigatuma iba ingenzi muri sisitemu yubumenyi nubuhanga.

Ibiranga:

1. Urusaku rwinshi-Ruto Urusaku: Rf cryogenic LNAs igera kumibare y urusaku ruri munsi ya kimwe cya cumi cya decibel (dB), bikaba byiza cyane kuruta ibyumba byubushyuhe bwicyumba. Ibi biterwa no kugabanuka kwurusaku rwubushyuhe kubushyuhe bwa cryogenic.
2. Inyungu nyinshi: Itanga ibimenyetso byerekana ibimenyetso byinshi (mubisanzwe 20-40 dB cyangwa irenga) kugirango byongere ibimenyetso bidakabije bitesha agaciro igipimo cyerekana urusaku (SNR).
3. Umuyoboro mugari: Shyigikira umurongo mugari wa radiyo, kuva kuri MHz nkeya kugeza kuri GHz nyinshi, ukurikije igishushanyo mbonera.
4. Guhuza Cryogenic: Microwave cryogenic yongerera urusaku rwinshi rwakozwe kugirango rukore neza mubushyuhe bwa kirogenike (urugero, 4K, 1K, cyangwa munsi). Yubatswe ukoresheje ibikoresho nibigize ibikoresho bikomeza amashanyarazi nubukanishi mubushyuhe buke.
5. Gukoresha ingufu nke: Gukoresha imbaraga nkeya kugirango wirinde gushyushya ibidukikije, bishobora guhungabanya sisitemu yo gukonjesha.
6. Igishushanyo cyoroheje kandi cyoroheje: Yashizweho kugirango yinjire muri sisitemu ya cryogenic, aho umwanya nuburemere bikunze kuba bike.

Porogaramu:

1. Yinjijwe muri dilutionrefrigerator kugirango ikore ku bushyuhe bwa milikelvin.

3. Ibikoresho bya elegitoroniki birenze urugero: mm wongeyeho urusaku rwinshi rwa urusaku rwinshi rukoreshwa mumashanyarazi hamwe na sensor kugirango byongere ibimenyetso bidakomeye mugihe bikomeza urusaku ruke, bigatuma ibimenyetso bitunganywa neza kandi bipimwa.

Qualwaveitanga Cryogenic Ntoya Urusaku rwinshi kuva DC kugeza 8GHz, kandi ubushyuhe bwurusaku burashobora kuba munsi ya 10K.
