Ma Amplifiers Otsika a Phokoso RF BroadBand EMC LNA Microwave Millimeter Wave High Frequency

1. Kukulitsa Mphamvu: LNA imatha kukulitsa mphamvu ya ma siginecha ofooka kufika pamlingo wokwanira kuti igwiritsidwe ntchito pa circuit kapena system. Mu kulumikizana opanda zingwe, siginecha yolandiridwa nthawi zambiri imakhala yofooka kwambiri, ndipo kudzera mu mphamvu ya LNA yokulitsa mphamvu, siginechayo imatha kukulitsidwa kufika pamlingo wodalirika kuti ipereke njira yogwirira ntchito komanso kuchotsedwa mphamvu pambuyo pake.
2. Kuchepetsa phokoso la makina: LNA imayesetsa kuchepetsa kuyambitsa phokoso lowonjezera pamene ikukulitsa chizindikiro. Phokoso ndi lofunika kwambiri pakugwira ntchito kwa makina olumikizirana opanda zingwe chifukwa limatha kubisa zizindikiro ndikuchepetsa chiŵerengero cha chizindikiro-ku-phokoso cha makinawo. Chojambulira phokoso lotsika la millimeter wave chimachepetsa phokoso la makina pochepetsa kuchuluka kwa phokoso pogwiritsa ntchito kapangidwe kabwino ka dera komanso zipangizo zotsika phokoso.
3. Kukonza mphamvu ya dongosolo: Ntchito ina ya LNA ndikukulitsa mphamvu ya dongosolo. Mphamvu ya dongosolo imatanthauza kuthekera kwa dongosolo kuthana ndi mphamvu ya ma signali amphamvu ndi ofooka nthawi imodzi. Ma amplifiers amphamvu okhala ndi phokoso lotsika amatha kuthana ndi mphamvu ya ma signali ofooka popanda kudzaza kwambiri kapena kusokoneza chifukwa cha mphamvu ya ma signali. Izi zimathandiza kuti dongosolo ligwire ntchito bwino m'malo omwe ali ndi mphamvu ya ma signali yosiyana kwambiri.

Magawo akuluakulu ogwiritsira ntchito LNA ndi kulumikizana popanda zingwe, zida zachipatala, zida zoyezera, radar, kulumikizana kwa satellite, ndi zina zotero.
