Introduction

The RX218T receiver module is a UHF ASK receiver/demodulator supporting ASK demodulation. It features high sensitivity (-108dBm), low power consumption (<6.5mA), and a wide dynamic range (greater than 60dB). The module employs a highly integrated chip with a built-in front-end LNA, mixer, filter, frequency synthesizer, and other circuits to maximize signal optimization.

Features

• ASK demodulation support, receive sensitivity up to -108 dBm
• Operating frequency: 315MHz (WL218T-3) / 433.92MHz (WL218T-4)
• Receive bandwidth: 300KHz
• Supply voltage input range: 2.2V~5.0V
• Low power consumption
• Excellent selectivity and spurious emission rejection, easy to pass CE/FCC international certification
• Excellent local oscillator radiation suppression; supports multiple receivers operating simultaneously (single transmitter, multiple receivers) without mutual interference or degraded reception range
• Maximum data rate 20Kbps, recommended data rate not exceeding 10Kbps
• Operating temperature range: -40~85°C, reliable operation in harsh environments
• Ultra-compact dimensions: 14.91×10.77×1 (mm)

Applications

• Wireless power switches and outlets
• Remote-controlled curtains, access control, and electric vehicles
• Security and surveillance systems
• Hotel room control
• Smart home products
