The LW103M-SR is a 300MHz to 930MHz receiver module employing super-regenerative amplitude-shift-keying (ASK) modulation (or On-Off keying, OOK) with superior receiving sensitivity. Customer can specify the receiving frequency and the factory will preset the receiving frequency accordingly. With our innovative design, the module can meet the FCC and ETSI EMI/EMC compliance requirements including the latest ETSI blocking requirement. Working together with LW203M, a transmitter module, LW103MSR will achieve a communication range of greater than 500 meters in open field. LW103M-SR is designed to operate for low power device (LPD) applications with demanding operating distance.
