Cryogenic Low Noise Amplifiers

Cryogenic Low Noise Amplifiers (LNAs) ndi zida zamagetsi zapadera zomwe zimapangidwira kukulitsa ma siginecha ofooka okhala ndi phokoso locheperako, pomwe zimagwira ntchito potentha kwambiri (nthawi zambiri kutentha kwamadzi a helium, 4K kapena pansi). Ma amplifiers awa ndi ofunikira kwambiri pamapulogalamu omwe kukhulupirika kwa ma siginecha ndi kukhudzika ndizofunikira kwambiri, monga quantumcomputing, zakuthambo wa wailesi, ndi zida zamagetsi zamagetsi. Pogwira ntchito pa kutentha kwa cryogenic, ma LNA amapeza phokoso lotsika kwambiri poyerekeza ndi anzawo omwe ali ndi kutentha kwa chipinda, kuwapangitsa kukhala ofunikira kwambiri pamakina olondola kwambiri asayansi ndiukadaulo.

Mawonekedwe:

1. Chithunzi cha Ultra-Low Phokoso: Rf cryogenic LNAs imakwaniritsa ziwerengero zaphokoso zotsika ngati magawo khumi a decibel (dB), omwe ali abwino kwambiri kuposa amplifiers a chipinda. Izi zimachitika chifukwa cha kuchepa kwa phokoso la kutentha pa kutentha kwa cryogenic.
2. Kupeza Kwambiri: Kumapereka kukweza kwa siginecha (nthawi zambiri 20-40 dB kapena kupitilira apo) kukulitsa ma siginecha ofooka popanda kuwononga chiŵerengero cha signal-to-noise (SNR).
3. Wide Bandwidth: Imathandizira ma frequency angapo, kuchokera ku MHz ochepa mpaka ma GHz angapo, kutengera kapangidwe kake ndi kagwiritsidwe ntchito.
4. Kugwirizana kwa Cryogenic: Ma Microwave cryogenic low phokoso amplifiers opangidwa kuti azigwira ntchito modalirika pa kutentha kwa cryogenic (mwachitsanzo, 4K, 1K, kapena ngakhale kutsika). Kumangidwa pogwiritsa ntchito zipangizo ndi zigawo zomwe zimasunga mphamvu zawo zamagetsi ndi makina pa kutentha kochepa.
5. Kugwiritsa Ntchito Mphamvu Zochepa: Kukometsedwa kuti zisawonongeke mphamvu zochepa kuti zisatenthedwe ndi chilengedwe cha cryogenic, chomwe chingasokoneze dongosolo lozizira.
6. Compact and Lightweight Design: Zopangidwira kuti ziphatikizidwe mu machitidwe a cryogenic, kumene malo ndi kulemera kwake kumakhala kochepa.
7. Mzere Wapamwamba: Imasunga umphumphu wa chizindikiro ngakhale pazigawo zamphamvu zolowetsa mphamvu, kuonetsetsa kuti mukukweza molondola popanda kusokoneza.

Mapulogalamu:

1. Quantum Computing: Millimeter wave cryogenic low noise amplifiers omwe amagwiritsidwa ntchito mu superconducting quantum processors kukulitsa zizindikiro zofooka zowerengera kuchokera ku qubits, zomwe zimathandiza kuyeza kolondola kwa quantum states. Kuphatikizika mu dilutionrefrigerators ntchito pa millikelvin kutentha.
2. Radio Astronomy: Amalembedwa ntchito m’zolandira ma telesikopu a wailesi kuti akweze zizindikiro zosaoneka bwino zochokera ku zinthu zakuthambo zakutali, kuwongolera kukhudzika ndi kuzindikira kwa zakuthambo.
3. Superconducting Electronics: ma mm wave cryogenic low noise amplifiers omwe amagwiritsidwa ntchito mu superconducting circuits ndi masensa kuti akweze zizindikiro zofooka pamene akukhalabe ndi phokoso laling'ono, kuonetsetsa kuti zizindikiro zolondola zikugwiritsidwa ntchito ndi kuyeza.
4. Kuyeza kwa Kutentha Kwambiri: Kugwiritsidwa ntchito muzokonza zofufuza za cryogenic, monga maphunziro a superconductivity, quantum phenomena, kapena kuzindikira zinthu zakuda, kukulitsa zizindikiro zofooka ndi phokoso lochepa.
5. Kujambula kwachipatala: Kugwiritsidwa ntchito muzithunzi zamakono monga MRI (Magnetic Resonance Imaging) yomwe imagwira ntchito pa kutentha kwa cryogenic kuti ipititse patsogolo khalidwe la chizindikiro ndi kuthetsa.
6. Kulankhulana kwa Space ndi Satellite: Kugwiritsidwa ntchito muzitsulo zozizira za cryogenic za zida zogwiritsira ntchito mlengalenga kuti zikweze zizindikiro zofooka kuchokera mumlengalenga, kupititsa patsogolo kulankhulana bwino ndi khalidwe la deta.
7. Particle Physics : Ogwiritsidwa ntchito mu cryogenic detectors pofuna kuyesa monga kuzindikira kwa neutrino kapena kufufuza kwakuda, kumene kukweza phokoso lapamwamba kwambiri ndikofunika kwambiri.

Qualwaveamapereka Cryogenic Low Noise Amplifiers kuchokera ku DC kupita ku 8GHz, ndipo kutentha kwa phokoso kumatha kukhala otsika ngati 10K.
