Geaneral Description:
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 Receiver offers a high level of integration
and needs only a few external components. The device containsa 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.
