The RXB2 is a miniature receiver module that receives On-off keyed ( OOK ) modulation signal and demodulated to digital signal for the next decoder stage. The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesiser, a crystal oscillator, a limiter with RSSI generator, a data filter, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life. The result is excellent performance in a simple-to-use, with a low external component count. The RXB2 is designed specifically for remote-control and wireless security receiver operating at 315Mhz in the USA under FCC Part 15 regulation.
