Attenuator chikamu chekudzora icho basa guru riri rekuderedza simba rechiratidzo rinopfuura nepa attenuator. Mukushandiswa kwaro, RF attenuators inogona kushanda munzvimbo dzakasiyana dzekupisa, zvichikonzera lcryogenic fixed attenuators. Takagadzira attenuators dzenzvimbo dzekupisa kwakaderera (-269~+125 degrees Celsius) nekusarudza zvinhu zvekugadzira uye kuvandudza tekinoroji.

Zvishandiso zveCryogenic fixed attenuators zvine conductivity yakanaka yekupisa uye kugadzikana kwakanyanya pakupisa kwakaderera zvakanyanya. Kune rumwe rutivi, chinodzivirira microwave chinogona kushandiswa sezvishandiso zve signal amplitude attenuators, uye kune rumwe rutivi, chinodzivirira chema millimeter wave chinogona kushandiswa sechinodziya chekupisa chekufambisa muchando. Chinodzivirira chema wave cheMm chinogona kushandiswa munzvimbo dzakadai sekutsvaga nzvimbo yakadzika, nyeredzi yeredhiyo, quantum computing, uye kutaurirana pasina waya, kunyanya mukuyedza kwefizikisi yekupisa kwakaderera uye kutsvagisa kwe superconductor.

Chinangwa:

1. Kuderedza Zviratidzo: Zvidziviriro zveCryogenic zvinoshandiswa kuderedza simba reRF nemasaini e microwave munzvimbo dzakanyanya kupisa. Izvi zvakakosha pakudzivirira michina inogamuchira zviri nyore uye kudzora mazinga emasaini.
2. Kudzora Ruzha: Nekuderedza ruzha, ruzha nekupindira kwemuchina zvinogona kuderedzwa, nokudaro zvichivandudza chiyero chesignal-to-noise (SNR) chechiratidzo.
3. Kufananidza Impedance: Zvidziviriri zveCryogenic fixed zvinogona kushandiswa kufananidza impedance yesystem, nokudaro zvichideredza kupenya uye mafungu akamira uye kuvandudza mashandiro esystem.

Kushandiswa:

1. Kuedza kweCryogenic physics: Mukuedza kwefizikisi yekupisa kushoma, ma "cryogenic fixed attenuators" anoshandiswa kudzora nekugadzirisa simba remasaini. Kuedza uku kunowanzo sanganisira kudzidza ma "superconductors", "quantum computing" nezvimwe zviitiko zvekupisa kushoma.
2. Tsvagiridzo yeSuperconductor: Mutsvagiridzo yesuperconductor, ma cryogenic fixed attenuators anoshandiswa kugadzirisa nekudzora mafrequency eredhiyo uye masaini e microwave kudzidza hunhu nemaitiro esuperconductors.
3. Quantum Computing: Muma quantum computing systems, cryogenic fixed attenuator inoshandiswa kudzora simba remasaini uye kudyidzana pakati pe quantum bits (qubits). Izvi zvakakosha kuti pave nekushanda kwe quantum computing kwakanyatsojeka.
4. Materesikopu eAstronomy neRadio: Mumasystem eteresikopu yeastronomy neradio, maRF attenuators anoshandiswa kugadzirisa simba rezviratidzo zvekudenga zvinogamuchirwa. Izvi zvinobatsira kuvandudza kunaka uye kururama kwedata rekutarisa.
5. Midziyo yemagetsi inopenya: Mumidziyo yemagetsi inodziya zvishoma, chinhu chinoderedza kupisa kwe microwave chinoshandiswa kudzora nekugadzirisa simba remasaini kuti chive nechokwadi chekuti michina inoshanda zvakanaka uye kuti inoshanda zvakanaka.
Muchidimbu, ma "cryogenic fixed attenuators" anoshandiswa zvakanyanya muminda yakawanda yakadai se cryogenic physics experiments, superconductor research, quantum computing, astronomy, uye cryogenic electronic equipment. Anovandudza mashandiro esystem uye kuvimbika kwayo nekudzora simba remasaini uye kuderedza ruzha.

Qualwaveinopa ma "high-precision cryogenic fixed attenuators" akasiyana-siyana anofukidza frequency range DC~40GHz. Simba repakati i2 watts. Ma "attenuators" anoshandiswa munzvimbo dzakawanda uko simba rinoda kuderedzwa.
