ASK Superheterodyne Wireless Receiver Module

Our ASK superheterodyne wireless receiver module is ideal for remote keyless entry, remote control curtain, wireless burglar security alarm, wireless industrial control system, wireless data transmission, etc. This product has a lot of features which are as follows.

1. Our wireless receiver module can be operated between -40 ℃ and 85 ℃. It works even at low temperatures.
2. It is easy to pass the CE or FCC international authentication, due to its high selectivity and good stray radiation inhibition function.
3. The good local oscillator radiation inhibition function enables multiple receiver modules to work together without affecting the receiving distance.
4. The receiver sensitivity is up to -112dBm.
5. In power save mode, this product consumes only 50nA.
6. Its input voltage ranges from 2.4V to 5.5V.
7. 315MHz or 433MHz frequency is available and specific frequency can be customized.
8. This product offers low power consumption. When frequency is 315MHz, its current is 2.7mA.
9. Its data transmission rate can be done to the lowest as 10Kbps.
