Low Noise Amplifier, Frequency 0.1~18GHz, Gain 30dB, Noise Figure 3dB

Low noise amplifier ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kukulitsa ma siginecha ofooka, omwe amagwiritsidwa ntchito kwambiri m'magawo monga kulumikizana, radar, zakuthambo za wailesi, ndi zina zambiri.

Makhalidwe:

1. Phokoso lochepa la phokoso
Chiwerengero chaphokoso chimagwiritsidwa ntchito pofotokoza kuchuluka kwa kuwonongeka kwa phokoso lachidziwitso cholowetsa ndi amplifier, ndipo ndi chisonyezo choyezera momwe phokoso limagwirira ntchito. Phokoso lochepa la phokoso limatanthawuza kuti amplifier imayambitsa phokoso lochepa kwambiri pamene ikukulitsa chizindikiro, chomwe chingasunge bwino chidziwitso choyambirira cha siginecha ndikuwongolera chiŵerengero cha chizindikiro ndi phokoso la dongosolo.
2. Kupindula kwakukulu
Kupindula kwakukulu kumatha kukulitsa zizindikiro zofooka zolowera kumtunda wokwanira wokonzekera dera lotsatira. Mwachitsanzo, mukulankhulana kwa satellite, zizindikiro za satana zimakhala zofooka kwambiri zikafika pamalo olandirira pansi, ndipo kupindula kwakukulu kwa amplifiers otsika phokoso kumatha kukulitsa zizindikirozi kuti ziwonongeke ndi kukonzanso.
3. Wide bandi kapena mwachindunji pafupipafupi gulu ntchito
Ma amplifiers otsika amatha kupangidwa kuti azigwira ntchito mu gulu lafupipafupi ndipo amatha kukulitsa ma siginecha pafupipafupi.
4. Mzere wapamwamba
Mzere wapamwamba wa amplifier otsika-phokoso umatsimikizira kuti mawonekedwe a mafunde ndi ma frequency a siginecha sasokonekera panthawi yokulitsa, kuwonetsetsa kuti ma siginechawa amatha kuchotsedwabe bwino ndikuzindikiridwa pambuyo pakukulitsa.

Ntchito:

1. Gawo loyankhulana
M'makina olumikizirana opanda zingwe, monga kulumikizana ndi mafoni am'manja, netiweki yamalo opanda zingwe (WLAN), ndi zina zotere, amplifier yaphokoso yotsika ndi gawo lofunikira pakumapeto kwa wolandila. Imakulitsa ma siginecha ofooka a RF omwe amalandilidwa ndi mlongoti kwinaku akuchepetsa kuyambika kwa phokoso, potero imakweza kukhudzika kwa njira yolumikizirana.
2. Dongosolo la radar
Pamene mafunde a electromagnetic otulutsidwa ndi radar amalumikizana ndi chandamale ndikubwerera ku cholandira cha radar, mphamvu ya chizindikiro imakhala yofooka kwambiri. Chokulitsa chaphokoso chochepa chimakulitsa zizindikiro zofooka za echo kumapeto kwa cholandirira cha radar kuti zithandizire kuzindikira kwa radar.
3. Zida ndi mamita
Pazida zina zoyezera bwino kwambiri zamagetsi, monga ma spectrum analyzers, sign analyzers, etc., amplifiers otsika phokoso amagwiritsidwa ntchito kukulitsa chizindikiro choyezera, kuwongolera kulondola kwa kuyeza komanso kumva kwa chida.

Qualwave Inc. imapereka gawo lotsika la amplifier kapena makina athunthu kuchokera ku DC kupita ku 260GHz. Ma amplifiers athu amagwiritsidwa ntchito kwambiri pama waya opanda zingwe, olandila, kuyesa kwa labotale, radar ndi magawo ena.
Nkhaniyi ikuwonetsa amplifier yotsika phokoso yokhala ndi ma frequency osiyanasiyana a 0.1 ~ 18GHz, phindu la 30dB, ndi chithunzi chaphokoso cha 3dB.
