Chinopa Ruzha Rushoma (LNA) chinowedzera ruzha chine nhamba yeruzha yakaderera zvikuru. Chinonyanya kushandiswa kuwedzera masaini asina simba ukuwo chichideredza kupindirana kweruzha kuti chiwedzere chiyero chesignal-to-noise. Chinowanzoiswa kumberi kwesystem yeredhiyo, senge mushure meantenna, kuti chiwedzere masaini asina simba anogamuchirwa kubva mumhepo.
Hunhu:
1. Ruzha Rwakaderera: Hunhu hukuru hweLow Noise Amplifier imhando yayo yeruzha rwakaderera zvikuru (Noise Figure, NF). Ruzha rwakaderera, kupindirana kweruzha kushoma kunounzwa neamplifier, zvichikonzera huwandu hwesignali-ku-ruzha hwakakwira.
2. Kuwana Kwakawanda: Kuti iwedzere zvinobudirira masaini asina simba, Chinosimudzira Ruzha Chakaderera chinowanzova nekuwedzera kwakanyanya, izvo zvinogona kuwedzera zvakanyanya amplitude yechiratidzo.
3. Bandwidth Yakafara: MaAmplifiers mazhinji eNoise Low akagadzirwa kuti ave neband yakawanda, anokwanisa kubata masaini pahuwandu hwakakura hwefrequency.
4. Kugadzikana Kwakanaka: Chinosimudzira Ruzha Chishoma chinofanira kuva nekugadzikana kwakanaka kudzivirira kuzunguzika kana chichishanda pamafrequencies akakwira.
MaAmplifaya eRuzha Rushoma anoshandiswa zvakanyanya mukutaurirana kusina waya, kutaurirana nesatellite, radar, electronic countermeasures, radio astronomy, nedzimwe nzvimbo.
Qualwave inopa akasiyana-siyana ma amplifiers ane ruzha rushoma kubva pa4K kusvika 260GHz, uye nhamba yeruzha inogona kudzika kusvika pa0.7dB.
Tinoisa imwe yadzo, ine mafrequency anotangira pa9KHz kusvika pa3GHz, kuwedzera kwe43dB, nhamba yeruzha ye3dB, P1dB ye16dBm.

Qualwave ine ruzivo rwemakore akawanda mukutsvaga nekugadzira ma amplifiers ane ruzha rushoma, izvo zvinogona kugadzira zvakawanda uye kugadzira tsvakiridzo yakagadziridzwa zvichienderana nezvinodiwa nevatengi.
Tinokugamuchirai kuti musiye meseji kuti muwane rumwe ruzivo.
