Attenuator chikamu chekudzora chine basa guru ndekudzora simba rekusimbisa parinopfuura nepakati. Mune zvinoshandiswa zvinoshanda, rf vatengesi vangashanda munzvimbo dzakasiyana tembiricha, vachipa kusimuka kune lcryogenic yakagadziriswa vateveri. Isu takagadzira vatendi vezvikamu zvekushambadzira tembiricha (-269 ~ + 125 degrees celsius) nekusarudza yakakodzera zvigadzirwa uye kugadzirisa mwero wehunyanzvi.

Cryogenic Yakagadziriswa vatengesi vane yakanaka yekudzivirira yekuita uye yakanyanya kugadzikana pakudziya kwakanyanya. Pane rumwe ruoko, microwave ettenuator inogona kushandiswa seyinasaina masaga eAntenuators, uye kune rumwe rutivi, millimeter wave MM wave wave

Chinangwa:

1. Signal Attenuation: Cryogenic Yakagadziriswa vateveri vanoshandiswa kurongedza zvine simba Simba reRF uye microwave signals mune yakaderera tembiricha tembiricha. Izvi zvakakosha kuti udzivirire zvakadzama kugamuchira zvishandiso uye kudzora chiratidzo masaini.
2. Ruzha Kudzora: Nekutonga chiratidzo, ruzha uye kukanganiswa muhurongwa kunogona kuderedzwa, nekukasira kuchiratidza-kune-ruzha ratio (snr) yechiratidzo.
3. Kufananidza kusakwana: Cryogenic yakagadziriswa vatengesi vanogona kushandiswa kufananidza kusakanganiswa kwehurongwa, nekudaro kuderedza kuratidzwa uye nekuvandudza mashandiro ehurongwa.

Chikumbiro:

1. Cruyogenic fizikisi kuyedza: mune yakaderera-tembiricha fizikisi, Cryogenic yakagadziriswa vatengesi vanoshandiswa kudzora uye kugadzirisa chiratidzo. Aya maedzo anowanzo kusanganisira kudzidza kwesimba reSuperconductors, huwandu hwekomputa uye imwe yakaderera-tembiricha phenomena.
2..
3. Quantum computing: muQuentum compomputer, Cryogenic Yakagadziriswa Attenuator inoshandiswa kudzora Simba reSignals uye kuwirirana pakati peVentum Bits (Quebits). Izvi zvakakosha pakuzadzisa yakakwira-chaiyo Quantum computer mabasa.
4. Astronomy terlecopes: Muzvikudzo uye radio teresicope masisitimu, rf vateresi vanoshandiswa kugadzirisa simba rekugamuchira masaini edenga. Izvi zvinobatsira kuvandudza kunaka uye kurongeka kwedata yekucherechedzwa.
5. Cryogenic Electronic Midziyo: Mune yakaderera-tembiricha yemagetsi zvishandiso, microwave extronuator inoshandiswa kudzora uye kugadzirisa sigine signal simba kuti ive yakajairika kushanda uye nekukasira mashandiro emidziyo.
Muchidimbu, Cryogenic Fifferors anoshandiswa zvakanyanya muminda yakawanda seClyogenic Fizzics Fizts, Superconductor Tsvagurudzo, kuongorora nyeredzi, uye cryogenic zvemagetsi zvemagetsi. Ivo vanovandudza maitiro ehurongwa uye kuvimbika nekuzvinyatso kudzora signal simba uye kuderedza ruzha.

Qualwaveinopa akasiyana-siyana yakakwirira chaiyo cryogenic yakagadziriswa vatengesi vanofukidza iyo frequency range ~ 40GHZ. Iyo avhareji simba ndeye 2 watts. Vatorwa vanoshandiswa mune akawanda mashandisirwo okuderedzwa kwesimba rinodiwa.
