Low Noise Amplifier Systems, 4~8GHz, Gain 40dB, Noise Figure (NF) 1.1dB

Dongosolo latsopano la phokoso la amplifier limathandizira kulandila kwamphamvu kwambiri. M'madera monga mauthenga opanda zingwe, kufufuza kwa radar, satellite navigation, ndi kuyeza kolondola, kukweza kwakukulu kwa zizindikiro zofooka kumakhalabe vuto lalikulu laukadaulo. Ndife onyadira kuyambitsa kachitidwe kathu kakang'ono ka amplifier (LNA) kamene kamakhala ndi phindu la 40dB, kutulutsa phokoso lapadera, kukhazikika kwabwino, komanso magwiridwe antchito ambiri kuti tipereke yankho lodalirika lakutsogolo lakutsogolo kwamagetsi apamwamba kwambiri. M'munsimu muli chidule cha mbali zake zazikulu ndi ntchito zake:

Zofunika Kwambiri:

1. Phokoso lotsika kwambiri
Pogwiritsa ntchito ukadaulo wotsogola wa semiconductor komanso mawonekedwe owongolera ozungulira, makinawa amakwaniritsa magwiridwe antchito amtundu wotsogola wamakampani, kupondereza bwino phokoso lachibadwidwe kuti zitsimikizire kulandila kwamphamvu kwa ma siginecha ofooka omwe ali oyenera kugwiritsa ntchito omwe ali ndi zofunikira zolimba za siginecha ndi phokoso.
2. Kupindula kwakukulu ndi mzere wapamwamba
Amplifier imapereka phindu lalikulu ndikusunga kukhulupirika kwa ma siginecha kudzera muukadaulo wowongolera masitepe angapo, ndikupereka mitundu yosiyanasiyana yosinthika yoyenera madera ovuta amagetsi.
3. Kufalikira kwa Wideband
Kuthandizira kugwira ntchito kuchokera kumayendedwe otsika kupita kumagulu a ma millimeter-wave, makinawa amapereka njira zosinthira pafupipafupi kuti zikwaniritse zosowa zosiyanasiyana pamalankhulidwe, radar, zakuthambo zamawayilesi, ndi zina zambiri.
4. Kukhazikika kwakukulu ndi kudalirika
Kulipila kwa kutentha komwe kumapangidwira komanso mabwalo okonda kukondera amatsimikizira kugwira ntchito mokhazikika pansi pa kutentha kosiyanasiyana komanso kugwira ntchito kwanthawi yayitali. Mapangidwe otetezedwa bwino a modular amalepheretsa kusokoneza kwakunja, ndikupangitsa kukhala koyenera madera ovuta.
5. Kuphatikiza ntchito kwanzeru
Njira zolumikizirana ndi digito (mwachitsanzo, SPI/I2C) zimathandizira kusintha kupindula kwakutali, kuyang'anira mawonekedwe, ndi kuzindikira zolakwika, kutsogoza kuphatikiza kosasinthika mumayendedwe oyesera okha kapena zida zolandirira mwanzeru.

Mapulogalamu Odziwika:

1. Malo olumikizirana opanda zingwe: Kumakulitsa chidwi cholandila mu machitidwe a 5G/6G, kuwongolera kufalikira kwa m'mphepete.
2. Makina a Satellite & Aerospace: Amathandizira kulandira ma siginecha a satellite ndi kufufuza kwakuya kwamtunda mu ultra-long-long, low-SNR environments.
3. Nkhondo ya radar & yamagetsi: Imakulitsa kuzindikira kofooka kwa chandamale, kukonza mawonekedwe a radar.
4. Zida za sayansi ndi zoyezera: Zimapereka kukwezera ma siginecha oyeretsedwa kwambiri pamatelesikopu a wailesi, kuyesa kwachulukidwe, ndi zina zambiri.
5. Zamagetsi zamagetsi: Zimathandizira kupeza chizindikiro cholondola mu MRI ndi machitidwe owunikira zizindikiro.

Qualwave Inc. imapereka makina okulitsa phokoso omwe amaphimba ma frequency a DC mpaka 110GHz pamapulogalamu osiyanasiyana. Nkhaniyi ikuwonetsa 4-8GHz LNA system yokhala ndi phokoso la 1.1dB.
