superheterodyne decoding receiver module

详情

GDRX****2A is a decoding wireless receive module with VHF/UHF . It has a widely application in automatic door system, auto-gates as retract type, factory automatic, communication, secretary system, GSM/GPS system, and other where need wireless remote control. It adopting SAW, has no regulable component, insure the frequency don�t excursion in anywhere, adopting SMT import component which have excellent stability, the frequency have no excursion or distance don�t change when librated or high/low temperature. It has excellent reliability and stability, can avoid the disadvantage of regenerative circuit which liable to be interfered and low reliability. This receiving system is a perfect choice where need high demand. Characteristic as follows&#****6; &#****8;1&#****9;The sensibility is excellent; the receiving distance is twice of others�. &#****8;2&#****9;It has reasonable receiving band width, strong anti-jamming, it can adapt to kinds of condition. &#****8;3&#****9;It has excellent ability of suppressing assemble or scattering radiation, easy pass kinds of instrument. &#****8;4&#****9;Due to excellent shield ,it can adapt kinds of installing environment, consistency is nicer. &#****8;5&#****9;It has ability to suppress the radiation, can worked with several modules (one transmitting module and several receiving module ), and have no interference to each other, and don�t influence the receiving distance. &#****8;6&#****9;Adopting the SAW, the frequency have no excursion when shaking or high/low temperature, the capability is immobile, and the temperature range is wide. &#****8;7&#****9;Enhance the anti-jamming ability from the mobile telephone, improve decoding waveform. &#****8;8&#****9;Frequency&#****6;**3 / **5MHz&#****0;
