Amplifier y'urusaku ruto (LNA), umurongo wa 9K ~ 1GHz, kongera 30dB, ikigereranyo cy'urusaku (NF) 2dB

Amplifier y'urusaku ruto ni igice cy'ingenzi muri sisitemu ya RF/micro-onde, ikoreshwa cyane cyane mu kongera ibimenyetso bidakomeye mu gihe igabanye urusaku rw'inyongera. Imirimo yayo y'ingenzi n'uburyo ikoreshwa ni ibi bikurikira:

Imirimo y'ingenzi:

1. Kongera ubushobozi bw'ibimenyetso
Ongera uburebure bw'amajwi adakomeye yakirwa na antene cyangwa sensor kugira ngo urebe ko imikorere yayo ikorwa neza n'insinga zikurikiraho nka mixers na ADCs.
2. Kugabanya urusaku
Mu kunoza igishushanyo no gukoresha ibikoresho bidakoresha urusaku ruke, ishusho y'urusaku yinjijwe ubwayo (NF) igenzurwa mu ntera iri hagati ya 0.5-3dB (indeal amplifier NF = 0dB).

Ingero z'Ikoreshwa:

1. Sisitemu ya radar
Muri radar ya gisirikare (nk'iradar igenzura inkongi y'umuriro mu kirere) na radar y'abasivili (nk'iradar y'imirasire y'imodoka), LNA ikoreshwa mu kongera ikimenyetso cy'ingufu (ikigereranyo cy'urusaku SNR < 0dB) kigaragazwa n'intego. Iyo inyuze mu buryo bwo kongera imbaraga hamwe na NF < 2dB, radar ishobora kumenya intego ifite RCS iri kure cyangwa iri hasi (igice cya radar).
2. Sisitemu y'itumanaho idakoresha umugozi
Amplifier y'urusaku ruto ni igice cy'ingenzi cya sitasiyo za 5G/6G, itumanaho rya satelite, n'imiyoboro yakira itumanaho rya telefoni zigendanwa. Ishinzwe kongera urusaku ruto (NF < 1.5dB) rw'ibimenyetso bya RF bidakomeye (bigera kuri -120dBm) byafashwe na antene mbere yo gukuraho ikimenyetso, bikongera cyane uburyo sisitemu yakira. Urugero, muri milimetero y'umuraba (24 - 100GHz), LNA ishobora kwishyura kugeza kuri 20dB y'igihombo cy'inzira, ikemeza ko kohereza amakuru ku muvuduko mwinshi bihamye.
3. Igikoresho cyo gupima neza cyane
Mu bikoresho nka spectrum analyzers na vector network analyzers (VNA), LNA igena mu buryo butaziguye imikorere y'urusaku rw'igikoresho n'uburyo gihinduka. LNA ishobora kunoza uburyo igikoresho gipima binyuze mu kongera ikimenyetso cyapimwe ku rwego rwa nV kugeza ku rugero rwiza rwa ADC (nka 1Vpp). Hagati aho, ultra-low noise coefficient (NF < 3dB) ishobora kugabanya neza uburyo ibipimo bitameze neza no kugabanya amakosa yo gupima.
4. Kwagura ahantu hakoreshwa
Ibyerekeye ikirere bya radiyo: Telesikope ya FAST ikoresha LNA ikonjeshejwe na heliyumu (NF ≈ 0.1dB) kugira ngo ifate imirongo ya spectral ya cm 21 mu isanzure.
Kubara kwa Quantum: Kongera ibimenyetso bya μV (4 - 8GHz) bya qubits zikora cyane bisaba imikorere y'urusaku rungana na quantum.
Ishusho y'ubuvuzi: Ibikoresho bya MRI byongera ibimenyetso bya μV bya magnetic resonance binyuze muri LNA itari magnetic, hamwe n'izamuka ry'ikigereranyo cy'urusaku kirenga 10dB.

Qualwave Inc. itanga amplifera z'urusaku ruri hasi kuva kuri 9kHz kugeza kuri 260GHz, hamwe n'urusaku ruri hasi nka 0.8dB.
Uburyo bwa QLA-9K-1000-30-20, bwagenewe by'umwihariko ubushakashatsi bwa siyansi n'itumanaho, bufite imikorere myiza cyane yo kwiyongera kwa 30dB n'umubare w'urusaku rwa 2dB muri 9kHz ~ 1GHz.
