0.01-1Ghz High Gain Low Noise Power Amplifier

Chojambulira cha phokoso lotsika kwambiri (LNA) chomwe chimagwira ntchito mkati mwa ma frequency a 0.01 mpaka 1GHz ndi gawo lofunikira kwambiri m'makina amakono olumikizirana ndi mapulogalamu ogwiritsira ntchito ma signal. Chipangizochi chapangidwa kuti chiwonjezere ma signal ofooka pamene chikuwonjezera phokoso lochepa, kuonetsetsa kuti ma signal ali bwino kwambiri kuti agwiritsidwe ntchito kapena kusanthula kwina.

LNA nthawi zambiri imakhala ndi zipangizo zapamwamba za semiconductor komanso njira zopangira ma circuit kuti ikwaniritse magwiridwe ake abwino kwambiri. Kupindula kwake, komwe kungakhale kwakukulu, kumalola kuti iwonjezere bwino ma signali popanda kusokoneza kwakukulu, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo omwe mphamvu ya signali ndi yolepheretsa, monga polumikizirana ndi satelayiti kapena ma transmissions opanda zingwe akutali.

Kugwira ntchito pa 0.01 mpaka 1GHz kumaphatikizapo ntchito zosiyanasiyana kuphatikizapo wailesi ya VHF/UHF, maulalo a microwave, ndi makina ena a radar. Bandwidth yayikulu ya amplifier imatsimikizira kuti ikugwirizana ndi miyezo yosiyanasiyana yolumikizirana ndi ma protocol, zomwe zimapangitsa kuti ikhale yosinthasintha pamapulatifomu osiyanasiyana komanso momwe imagwiritsidwira ntchito.

Kuwonjezera pa kuchuluka kwa phokoso komanso kuchuluka kwa phokoso lochepa, zina zofunika kwambiri pa ma amplifiers awa ndi monga kufananiza kwa input ndi output impedance, linearity, ndi kukhazikika pa kusintha kwa kutentha. Zinthu izi pamodzi zimathandiza kuti zikhale zodalirika komanso zogwira mtima posunga umphumphu wa chizindikiro pansi pa mikhalidwe yosiyanasiyana.

Ponseponse, chokwezera phokoso lotsika kwambiri chomwe chili mkati mwa ma frequency a 0.01-1GHz ndichofunikira kwambiri pakukweza kukhudzidwa ndi magwiridwe antchito a njira zolumikizirana ndi kuzindikira, zomwe zimathandiza kulandira ndi kutumiza ma signal momveka bwino komanso modalirika.
