GDRX-2272A 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 dont excursion in anywhere, adopting SMT import component which have excellent stability, the frequency have no excursion or distance dont 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:
1. The sensibility is excellent; the receiving distance is twice of others.
2. It has reasonable receiving band width, strong anti-jamming, It can adapt to kinds of condition.
3. It has excellent ability of suppressing assemble or scattering radiation, easy pass kinds of instrument.
4. Due to excellent shield , it can adapt kinds of installing environment, consistency is nicer.
5. 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 dont influence the receiving distance.
6. Adopting the SAW, the frequency have no excursion when shaking or high/low temperature, the capability is immobile, and the temperature range is wide.
7. Enhance the anti-jamming ability from the mobile telephone, improve decoding waveform.
