LW103 is a super-regenerative amplitude-shift-keying (ASK) modulation (or On-Off keying, OOK) single chip receiver. It is designed to operate for low power device (LPD) applications. Industry commonly uses 315MHz, 433 MHz 886MHz and 915MHz for US and European markets for LPD applications. With our innovative design, the IC meets the FCC and ETSI EMI/EMC compliance requirements including the latest ETSI blocking requirement1. By changing a few external components, energy saving LW103 can support frequency band from 300MHz to 928MHz at low cost.
