Introduction

The RX18211 receiver module is a UHF-band ASK receiver/demodulator supporting ASK/OOK demodulation. It features high sensitivity (-112dBm), low power consumption (<6mA), and a wide dynamic range (greater than 60dB). The module employs a highly integrated chip with built-in front-end LNA, mixer, filter, frequency synthesizer, and other circuits to maximize signal optimization.

Features

• ASK demodulation support, receive sensitivity up to -112dBm
• Operating frequency: 315MHz (RX18211-3) / 433.92MHz (RX18211-4)
• Receive bandwidth: 300KHz
• Supply voltage input range: 2.0V - 5.0V
• Low power consumption: 4.58mA/3.3V @ 315MHz, 5.38mA/3.3V @ 433.92MHz
• Excellent selectivity and spurious emission rejection, easy to pass CE/FCC certification
• Excellent local oscillator radiation suppression; supports multiple receiver modules operating simultaneously (single transmitter, multiple receivers) without mutual interference or degradation of reception range
• Maximum data rate 5Kbps, recommended data rate not exceeding 5Kbps
• Temperature range: -10 - 60℃, reliable operation even in harsh ambient temperatures
• Ultra-compact dimensions: 31.5×11.8×1.0 (mm)

Applications

• AC/DC motor applications: rolling shutters, DC tubular motors, etc.
• Remote Keyless Entry (RKE) systems
• Smart home and building automation/surveillance
• Industrial inspection and control systems
• Long-range RFID
