LW120M is a miniature receiver module that receives on-off keying (OOK) modulation signal and demodulates to digital signal, which would be processed by a decoder on the next stage. Local Oscillator is made of PLL structure. The result is an outstanding performance and easy to use, with very few external components. LW120M is designed specifically for remote control and wireless receiver security operating at 315/433.92Mhz in the USA under FCC Part 15 regulation.
