Introduction

WL550 is a low-power, high-performance, plug-and-play OOK RF receiver IC. It features a wide supply voltage range of 2.5V to 5.5V, sensitivity up to -109dBm, operating frequency range of 300MHz to 480MHz, and supports data rates from 1Kbps to 5Kbps. Housed in a SOP8 package, the application circuit requires only an antenna impedance matching network, VDD decoupling capacitors, and AGC filter capacitors — no additional overshoot protection resistor is needed on the VDD line, helping to reduce overall application cost.
