RXB8 is a high quality superheterodyne receiver module withVHF/UHF. The module is based upon markets’ feedback and a lot ofcustomers’ advice. Its shocked in the electronic products market.The module adopting LSI circuit with high frequency and low noisewhich import from famous company of Europe. It has strongantistatic protection, high reliability and competitive price. Itswidely used in remote garage door, autogates as retract type,brakes, GSM/GPS system, factory automatic, communication andsecurity system etc.  Characteristic as follows:  (1) Thesensibility is up to -115dbm; the receive distance is twice ofothers  (2) Working Current: 10mA  Working Voltage:2.7V-5V (3) Dimension: 33cm(L)*14.5cm(W)*5cm(H) (4) Ithas reasonable receive band width, excellent ability of suppresscoordinate frequency, strong anti-jamming, it can adapt to kinds ofcondition.  (5) It has excellent ability of suppress assembleor scatter radiation, easy pass kinds of FCC or CE certification.  (6) It has ability to restrain the radiation, canworked with several module (one transmitting module and severalreceiving module) at the same time, and have no interference toeach other, and don’t influence the receiving distance.  (7)Adopting the SAW, the capability is immobile, and the temperaturerange is wide.  (8) Frequency range is 250-450 MHz, easy toadjust.  (9) Use microprocessor directly link, bit-rate can beup to 20kbps.  (10) Enhance the anti-jamming ability for themobile telephone, improve decoding waveform.  (11) Frequency:433 / 315MHz
