Cryogenic Noise Amplifiers

ʻO nā Cryogenic Low Noise Amplifiers (LNAs) he mau mea uila kūikawā i hoʻolālā ʻia e hoʻonui i nā hōʻailona nāwaliwali me ka liʻiliʻi i hoʻohui ʻia ka walaʻau, ʻoiai e hana ana ma nā wela haʻahaʻa loa (maʻamau ka wela helium wai, 4K a i lalo paha). He mea koʻikoʻi kēia mau mea hoʻonui i nā noi kahi i koʻikoʻi ai ka pono o ka hōʻailona a me ka naʻau, e like me ka quantumcomputing, radio astronomy, a me nā mea uila superconducting. Ma ka hana ʻana i nā mahana cryogenic, loaʻa nā LNA i nā helu haʻahaʻa haʻahaʻa haʻahaʻa loa i ka hoʻohālikelike ʻana i ko lākou mau hoa wela lumi, e lilo lākou i mea nui i nā ʻōnaehana ʻepekema a me ka ʻenehana kiʻekiʻe.

Nā hiʻohiʻona:

1. Kiʻi Leo Haʻahaʻa Haʻahaʻa: Loaʻa nā LNA cryogenic Rf i nā helu leo haʻahaʻa e like me ka hapaʻumi o kahi decibel (dB), ʻoi aku ka maikaʻi ma mua o nā mea hoʻonui wela o ka lumi. Ma muli o ka emi ʻana o ka walaʻau wela i nā mahana cryogenic.
2. Loaʻa kiʻekiʻe: Hāʻawi i ka hoʻonui hōʻailona kiʻekiʻe (maʻamau 20-40 dB a i ʻole) e hoʻoikaika i nā hōʻailona nāwaliwali me ka hoʻohaʻahaʻa ʻole i ka ratio signal-to-noise (SNR).
3. ʻO ka Bandwidth ākea: Kākoʻo i kahi ākea o nā alapine, mai kahi liʻiliʻi MHz a i kekahi mau GHz, ma muli o ka hoʻolālā a me ka noi.
4. Cryogenic Compatibility: Microwave cryogenic haʻahaʻa leo amplifiers i hoʻolālā ʻia e hana me ka hilinaʻi ma nā mahana cryogenic (e laʻa, 4K, 1K, a i ʻole lalo). Kūkulu ʻia me ka hoʻohana ʻana i nā mea a me nā ʻāpana e mālama i ko lākou mau pono uila a me nā ʻenehana i nā haʻahaʻa haʻahaʻa.
5. ʻO ka hoʻohana ʻana i ka mana haʻahaʻa: ʻoi aku ka maikaʻi no ka liʻiliʻi o ka hoʻoheheʻe ʻana i ka mana e pale i ka hoʻomehana ʻana i ke kaiapuni cryogenic, hiki ke hoʻopau i ka ʻōnaehana hoʻomaha.
6. Hoʻolālā Paʻa a Māmā: Hoʻolālā ʻia no ka hoʻohui ʻana i nā ʻōnaehana cryogenic, kahi i kaupalena pinepine ʻia ai ka lewa a me ke kaumaha.
7. Linearity kiʻekiʻe: E mālama i ka hōʻailona hōʻailona ma nā pae mana hoʻokomo kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hoʻonui pololei me ka ʻole o ka distortion.

Nā noi:

1. Quantum Computing: Millimeter wave cryogenic haʻahaʻa leo amplifiers i hoʻohana ʻia i ka superconducting quantum processors e hoʻonui i nā hōʻailona heluhelu nāwaliwali mai nā qubits, e hiki ai ke ana pololei i nā mokuʻāina quantum. Hoʻohui ʻia i loko o nā pahu hau hoʻoheheʻe e hana ma nā wela millikelvin.
2. Radio Astronomy: Hoʻohana ʻia i loko o nā mea hoʻokipa cryogenic o nā kelepona lekiō e hoʻonui i nā hōʻailona nāwaliwali mai nā mea lani mamao, e hoʻomaikaʻi i ka naʻau a me ka hoʻonā ʻana o nā ʻike hōkū.
3. Superconducting Electronics: mm hawewe cryogenic haʻahaʻa haʻahaʻa leo amplifier i hoʻohana 'ia i ka superconducting kaapuni a me nā sensors e hoʻonui i nā hōʻailona nāwaliwali i ka mālamaʻana i nā haʻahaʻa haʻahaʻa haʻahaʻa, e hōʻoiaʻiʻo ana i ka hana hōʻailona pololei a me ke ana.
4. Nā Hoʻokolohua Haʻahaʻa Haʻahaʻa: Hoʻohana ʻia i nā hoʻonohonoho noiʻi cryogenic, e like me ke aʻo ʻana o ka superconductivity, quantum phenomena, a i ʻole ka ʻike mea ʻeleʻele, e hoʻonui i nā hōʻailona nāwaliwali me ka leo liʻiliʻi.
5. Ke Kiʻi Lapaʻau: Hoʻohana ʻia i nā ʻōnaehana kiʻi kiʻi kiʻi e like me MRI (Magnetic Resonance Imaging) e hana ana i nā mahana cryogenic e hoʻonui ai i ka maikaʻi o ka hōʻailona a me ka hoʻonā.
6. Ka Lewa a me ka Satellite Communication: Hoʻohana ʻia i loko o nā ʻōnaehana hoʻoheheʻe cryogenic o nā mea kani e hoʻonui ai i nā hōʻailona nāwaliwali mai kahi hohonu, e hoʻomaikaʻi i ka maikaʻi o ke kamaʻilio a me ka maikaʻi o ka ʻikepili.
7. Particle Physics: Hoʻohana ʻia i loko o nā mea ʻike cryogenic no nā hoʻokolohua e like me ka ʻike neutrino a i ʻole ka ʻimi ʻeleʻele, kahi mea koʻikoʻi ka hoʻonui ʻana i ka leo haʻahaʻa.

Kaʻaleʻaleʻalako Cryogenic Low Noise Amplifiers mai DC a hiki i 8GHz, a hiki i ka haʻahaʻa o ka leo e like me 10K.
