0.01-1Ghz kupindula kwakukulu kwa Low Noise Power Amplifier

Chokulitsa phokoso chochepa kwambiri (LNA) chomwe chimagwira ntchito pakati pa 0.01 mpaka 1GHz ndi gawo lofunikira kwambiri pamakina amakono olankhulirana komanso kugwiritsa ntchito zizindikiro. Chipangizochi chapangidwa kuti chiwongolere ma siginecha ofooka kwinaku chikubweretsa phokoso locheperako, kuwonetsetsa kuti ma siginecha ali abwino kwambiri kuti asinthidwenso kapena kusanthula.

LNA nthawi zambiri imakhala ndi zida zapamwamba za semiconductor ndi njira zamapangidwe ozungulira kuti zikwaniritse mawonekedwe ake apadera. Kupindula kwake, komwe kungakhale kokulirapo, kumalola kuti ikweze bwino ma siginecha popanda kupotoza kwakukulu, ndikupangitsa kuti ikhale yabwino kugwiritsidwa ntchito m'malo omwe mphamvu yazizindikiro imakhala yolepheretsa, monga kulumikizana kwa satellite kapena kutumizirana ma waya mtunda wautali.

Kugwira ntchito mopitilira 0.01 mpaka 1GHz frequency band kumakhudza ntchito zambiri kuphatikiza wailesi ya VHF/UHF, maulalo a microwave, ndi makina ena a radar. Kuchuluka kwa bandwidth ya amplifier kumatsimikizira kuti kumagwirizana ndi njira zosiyanasiyana zoyankhulirana ndi ma protocol, kupititsa patsogolo kusinthika kwake pamapulatifomu osiyanasiyana ndikugwiritsa ntchito.

Kuphatikiza pa kupindula kwakukulu komanso kutsika kwaphokoso, zofunikira zina za amplifierswa zikuphatikiza kufananiza ndi kutulutsa kwa impedance, mizere, komanso kukhazikika pakusintha kwa kutentha. Zikhumbozi pamodzi zimathandizira kuti zikhale zodalirika komanso zogwira mtima posunga umphumphu wa zizindikiro pansi pa zinthu zosiyanasiyana.

Ponseponse, amplifier yotsika kwambiri yopeza phokoso mkati mwa 0.01-1GHz pafupipafupi ndiyofunikira pakuwongolera kukhudzidwa ndi magwiridwe antchito a njira zoyankhulirana ndi kuzindikira, zomwe zimapangitsa kuti zizimveka bwino komanso zodalirika polandila ndi kutumiza.
