RFM220LS/B/D ASK/OOK Receiver Module

Product Overview

RFM220LS/B/D is a low-cost ASK/OOK

receiver module based on a high-performance

CMT2220LS chip. Its operating frequency is

315MHz or 433.92MHz (the operating

frequency can be customized in the range of

300MHZ-480MHZ). Its operating voltage is

3.0V-5.5V. The receiver module has stable

performance, low power consumption, high

sensitivity and high cost - effectiveness, and

can be widely used in all kinds of data

transmission systems.

This specification only describes the basic

functions and performance parameters for this

receiver module, and for further information,

please refer to the CMT2220LS chip datasheet.
