RX500 433MHz superheterodyne RF receiver module For ASK/OOK modulation

Description

Here are the key specifications for the RX500 433MHz RF Receiver Module.

RX500 receiver module is receiving the UHF ASK demodulation equipment, support ASK demodulation. The receiver module has high sensitivity (-110dBm), low power consumption performance (<6mA), and a high dynamic range (greater than 60dB). The receiving 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.

Features

RX500 receiver module has high sensitivity (-110dBm) and support ASK demodulation;
Frequency: 315MHz(RX500-3) / 433.92MHz(RX500-4);
Bandwidth 300KHz;
Wide operating voltage range: 2.0V-5.0V;
Low power consumption;
Good selectivity and spurious radiation suppression, Can pass CE / FCC international certification easily;
Good local oscillator radiation suppression ability, multiple receiver modules can work together (single transmitter and multiple receivers) and will not interfere with each other, and use together does not affect the receiving distance;
The maximum communication rate is 10Kbps;
Temperature range: -40-85℃, it can work normally even in harsh environmental temperature;
Small Size: 23.5 x 9 x 1.0 (mm)

APPLICATION
Wireless power switch and socket;
Wireless remote control curtains, wireless access control, electric vehicles;
Security, monitoring system;
Hotel room control;
Smart home products;

 Important Notes

1. Antenna: Requires an external antenna for optimal range. A 17cm straight wire or a helical coil (9 turns, 10mm diameter) is recommended for 433MHz .

2. Power Supply Filtering: As an RF device, it is sensitive to power supply noise. Add a 100nF ceramic capacitor and a 10µF electrolytic capacitor close to the VDD pin for stable operation
