Iyo yakaderera ruzha amplifier inowanzo shandiswa seyepamusoro-frequency kana yepakati-frequency preamplifier kune akasiyana marudzi eredhiyo anogashira, pamwe nekusimudzira maseketi e-high-sensitivity yemagetsi yekuona michina. Kana uchikwidziridza masaini asina simba, ruzha rwunogadzirwa neamplifier runogona kukanganisa zvakanyanya chiratidzo. Naizvozvo, zvinotarisirwa kudzikisa ruzha urwu kuvandudza chiratidzo-kune-ruzha reshiyo yezvakabuda. Kudzikira kwechiratidzo-kune-ruzha reshiyo inokonzerwa neamplifier inowanzo ratidzwa neruzha nhamba F.
Low-ruzha amplifiers chinhu chakakosha chedunhu rekugamuchira, iro rinogadzira uye rinoshandura chiratidzo chakagamuchirwa muruzivo. MaLNA anoitirwa kuve padyo nemudziyo wekugamuchira kuitira kuderedza kukanganisa kurasikirwa. Ivo vanongopa hushoma hweruzha (data risingabatsiri) kune yakagamuchirwa siginecha sezvo chero ichizosvibisa zvakanyanya iyo yatove isina simba chiratidzo. LNA inoshandiswa kana chiratidzo-ku-ruzha reshiyo (SNR) yakakwira uye inoda kudzikiswa ne50% uku simba richiwedzerwa. Chinhu chekutanga chemugamuchiri kubata chiratidzo iLNA, zvichiita kuti ive chinhu chakakosha mukuita kwekutaurirana.
Zvishandiso zveyakaderera-ruzha amplifier
LNA yakaona kuvandudzwa kwekutanga kwemvura helium-yakatonhorera parametric amplifiers uye tembiricha yekamuri parametric amplifiers. Nekukurumidza kuvandudza tekinoroji, yakatsiviwa nemicrowave field-effect transistor amplifiers mumakore achangopfuura. Iyi mhando yeamplifier ine yakanakisa hunhu hwehukuru hudiki, mutengo wakaderera, uye huremu. Kunyanya maererano neredhiyo frequency maitiro, ine hunhu hweruzha rwakaderera, yakakura frequency bhendi, uye kuwana kwakanyanya. Yakave ichishandiswa zvakanyanya muC, Ku, Kv, uye mamwe ma frequency mabhendi. Uye tembiricha yeruzha yeanowanzo shandiswa yakaderera-ruzha amplifiers inogona kudzikira pane 45K.
Thelow noise amplifier (LNA) inonyanya kugadzirirwa nharembozha yekutaurirana zvivakwa base station application, senge transceiver isina waya yekutaurirana makadhi, tower-mounted amplifiers (TMA), masanganisi, anodzokorora, uye kure / dijitari wireless Broadband head-end equipment. Yakaderera ruzha nhamba (NF, Noise Figure) yakaisa mwero mutsva. Parizvino, iyo isina waya yekutaurirana indasitiri indasitiri yakatarisana nedambudziko rekupa yakanakisa chiratidzo chemhando uye kuvharika mune yakazara vanhu. Receiver senitivity ndechimwe chezvakanyanya kukosha zvinodiwa mukugadzirwa kweiyo base station yekugamuchira nzira. Iyo yakakodzera LNA kusarudzwa, kunyanya yekutanga Level LNA inogona kuvandudza zvakanyanya kuita kwekunzwa kwevagashi chiteshi vanogamuchira, uye yakaderera ruzha index zvakare yakakosha dhizaini chinangwa.
Kana uine chero zvaunoda zveLNA, kugamuchirwa kubvunza: sales@cdjx-mw.com.
