Description
The RX480A receiver module is a UHF ASK receiver demodulator that supports ASK and OOK modulation. The receiver module has high sensitivity (-107dBm), low power consumption, and high dynamic range (more than 60dB). The module uses a highly integrated chip, built-in front-end low noise amplifiers, mixers, filters, frequency synthesizer and other circuits, can maximize the signal optimization.
According to different application requirements, RX480 series receiving modules have the following products according to the working voltage and working frequency:
2, product characteristics
Support ASK/OOK modulation method, the receiving sensitivity reaches -107dBm;
Operating frequency: 315 MHz, 433.92 MHz, bandwidth about ±150KHz;
Supply voltage input range: 2.2V-5.0V;
Good selectivity and stray radiation suppression capabilities, easy to pass CE/Fcc international certification;
Good local oscillator radiation suppression ability, can work together with multiple receiver modules (ie, single-shot and multiple-receiving) and does not interfere with each other. Using together does not affect the receiving distance.
Temperature range: -40-85°C Normal operation even in harsh ambient temperatures
Ultra-small size (customizable according to customer requirements).
