433 Mhz Superheterodyne RF Receiver Module and Transmitter Module with Antenna for Arduino DIY Kit 433Mhz Remote Controls
1. Product description
     The RX470 receiving module is a UHF ASK receiving demodulator, which supports ASK and OOK modulation methods. The receiving module has high sensitivity (-108dBm), low power consumption performance, and a high dynamic range (greater than 60dB). The module uses a highly integrated chip, built-in front-end low-noise amplifier, mixer, filter, frequency synthesizer and other circuits, which can optimize the signal to the greatest extent.
2. Product features
Support ASK/OOK modulation mode, the receiving sensitivity reaches -108dBm;
Working frequency: 315 MHz, 433.92 MHz, bandwidth is about ±150KHz;
Power supply voltage input range: 2.2V-5.0V;
Good selectivity and stray radiation suppression ability, easy to pass CE/Fcc international certification;
Good local oscillator radiation suppression ability, multiple receiving modules can work together (that is, single-transmit and multiple-receive) and will not interfere with each other, and use together does not affect the receiving distance;
Temperature range: -40-85, it can work normally even in harsh environmental temperature;
Ultra-small size (can be customized according to customer needs).
3. Scope of application
Wireless power switch, socket
Remote control curtains, access control, electric cars
Security, monitoring system
Hotel room control
Smart home products
4. Package and pin arrangement
Pin-in module RX470-4
5. Antenna size
