China Kingtone inopa Mutengo Unoshanda Wevanhu Kuchengetedzwa TETRA, iDEN 800 MHz Band Frequency 806-821/851-866 MHz Repeater BDA Bi-Directional Amplifier yeKukurukurirana Kwakakosha.
TETRA 800MHz +33dBm Off-air Bi-Directional Amplifier(BDA) system yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station (BTS).Kunyanya kushanda kweRF Repeaters system kugashira yakaderera-simba siginecha kubva kuBTS kuburikidza neredhiyo frequency transmission uye wobva waendesa chiratidzo chakasimudzirwa kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.
Main Features
◇ High linearity PA;High system kuwana;
◇ Intelligent ALC tekinoroji;
◇ Yakazara duplex uye yakakwirira kuzviparadzanisa kubva kumusoro kumusoro kuenda kudownlink;
◇ otomatiki Operation nyore kushanda;
◇ Maitiro akabatanidzwa ane kuita kwakavimbika;
◇ Yemunharaunda uye kure yekutarisa (isarudzo) ine otomatiki kukanganisa alarm & kure kure;
◇ dhizaini yemamiriro ekunze ekuisa zvese-mamiriro ekunze;
Yakajairika application:
Mu-kuvaka ruzhinji chengetedzo isina waya network wideband iDEN Repeater 800MHz (806-821MHz / 851-866MHz ) BDA Repeater Amplifier
kuwedzera kuvharwa kwechiratidzo chenzvimbo dzemapofu kana chiratidzo chisina kusimba kana chisipo.
