Low Noise Amplifier (LNA) ndi amplifier yokhala ndi phokoso lotsika kwambiri. Amagwiritsidwa ntchito makamaka kukulitsa ma siginecha ofooka pomwe amachepetsa kusokoneza kwa phokoso kuti apititse patsogolo chiwongolero cha ma sign-to-phokoso. Nthawi zambiri imayikidwa kumapeto kwa pulogalamu yolandirira wailesi, monga pambuyo pa mlongoti, kukulitsa zizindikiro zofooka zomwe zimalandiridwa kuchokera mlengalenga.
Makhalidwe:
1.Low Noise Figure: Chikhalidwe chachikulu cha Low Noise Amplifier ndi phokoso lochepa kwambiri (Noise Figure, NF). Kutsika kwa phokoso, phokoso lochepa lomwe amplifier limayambitsa, zomwe zimapangitsa kuti phokoso likhale lokwera kwambiri.
2.Kupeza Kwambiri: Pofuna kukulitsa bwino zizindikiro zofooka, Low Noise Amplifier nthawi zambiri imakhala ndi phindu lalikulu, lomwe lingathe kuwonjezera kwambiri matalikidwe a chizindikirocho.
3.Wide Bandwidth: Ma Amplifiers Ambiri Otsika Phokoso amapangidwa kuti akhale otambalala, otha kunyamula ma siginecha kudutsa ma frequency angapo.
4.Kukhazikika Kwabwino: Kutsika kwa Noise Amplifier kumafunika kukhala ndi kukhazikika kwabwino kuti zisawonongeke pamene zikugwira ntchito pamtunda wapamwamba.
Low Noise Amplifiers amagwiritsidwa ntchito kwambiri polankhulana opanda zingwe, satellite communication, radar, electronic countermeasures, radio astronomy, ndi zina.
Qualwave imapereka ma amplifiers osiyanasiyana otsika kuchokera ku 4K mpaka 260GHz, ndipo phokoso limatha kukhala lotsika ngati 0.7dB.
Timayambitsa imodzi mwa izo, ndi ma frequency oyambira 9KHz mpaka 3GHz, phindu la 43dB, chithunzi chaphokoso cha 3dB, P1dB cha 16dBm.

Qualwave apeza zaka zambiri pa kafukufuku ndi chitukuko cha amplifiers otsika-phokoso, omwe amatha kukwaniritsa kupanga kwakukulu ndi kufufuza ndi chitukuko malinga ndi zosowa za makasitomala.
Takulandirani kuti musiye uthenga kuti mudziwe zambiri.
