A Low Noise Amplifier (LNA) iri amplifier ine yakaderera ruzha chimiro. Inonyanya kushandiswa kukwidziridza masaini asina simba uku ichideredza kukanganiswa kweruzha kuvandudza chiratidzo-ku-ruzha reshiyo. Iyo inowanzoiswa kumucheto kumberi kweredhiyo inogamuchira system, senge mushure meantenna, kukwidziridza masaini asina simba anogamuchirwa kubva kumhepo.
Hunhu:
1.Low Noise Figure: Chimiro chepakati cheLow Noise Amplifier ndicho chimiro chayo chakanyanya kuderera (Noise Figure, NF). Iyo yakaderera nhamba yeruzha, kushomeka kweruzha kunokanganisa iyo amplifier inosuma, zvichikonzera yakakwira chiratidzo-ku-ruzha reshiyo.
2.Kuwana Kwepamusoro: Kuti unyatso kusimudzira zviratidzo zvisina simba, Low Noise Amplifier inowanzova nepamusoro, iyo inogona kuwedzera zvakanyanya amplitude yechiratidzo.
3.Wide Bandwidth: Mazhinji Low Noise Amplifiers akagadzirwa kuti ave wideband, anokwanisa kubata masaini pane yakafara frequency renji.
4.Kugadzikana Kwakanaka: A Low Noise Amplifier inoda kuva nekugadzikana kwakanaka kudzivisa oscillation kana uchishanda pamhepo yakakwirira.
Low Noise Amplifiers anoshandiswa zvakanyanya mukutaurirana pasina waya, satellite kutaurirana, radar, zvemagetsi countermeasures, radio astronomy, uye mamwe minda.
Qualwave inopa akasiyana-siyana akaderera ruzha amplifiers kubva ku4K kusvika 260GHz, uye iyo ruzha nhamba inogona kunge yakaderera se0.7dB.
Isu tinosuma imwe yacho, ine mafrequency kubva ku9KHz kusvika 3GHz, kuwana kwe43dB, ruzha nhamba ye3dB, P1dB ye16dBm.
