ASK/FSK Superheterodyne Wireless Receiver Module

ASK or FSK superheterodyne wireless receiver module shares a universal wireless receiver module RCT01TRXB15. With the adoption of the automotive-grade RF wireless data receiver chip, it offers the highest sensitivity and strong anti-interference ability, with wireless signal input to the data signal output without any external circuit. Thanks to its superior performance, it is selected as the RKE or BCM system of automotive. Users only need to decode the data through a simple circuit and then any wireless product development can be easily achieved. In addition, this product is also ideal for data communication system, remote control system, intelligent home system, wireless data transmission, wireless burglar alarm system, wireless industrial control system, and tire pressure monitoring system, etc.

Features and Advantages
1.This superheterodyne wireless receiver module provides the receiver sensitivity of up to -118dBm.
2. It works with 315 MHz and 433 MHz frequency. Other specific frequencies can be customized.
3. The input voltage of power is between 3.6 V and 5.5V.
4. In power save mode, it consumes only 10nA.
5. It has a low power consumption of 4.6mA.
6. Both ASK and FSK modes are available.
7. Our product can be operated at the industrial temperature range of-40 ℃ to 85 ℃. It can work even at extremely low temperature.
8. Thanks to its high selectivity and good stray radiation inhibition function, our product is not difficult to pass a series of authentications.
9. The good local oscillator radiation inhibition function enables multiple receiver modules to work together without affecting the receiving distance.

Explanation of RCT01TRXB15-433.92MHZ
1. RX stands for receiving data.
2. B refers to the version number of module.
3. The letter 15 stands for the chip used by this product.
4. 433.92MHZ is the operating frequency of our product.

Notes: Data output of RCT01TRXB15 module comes with low current. If the single chip microcomputer is directly driven, the I/O interface of single chip microcomputer should not connect with pull up or down resistors. Also, the pull up or down resistors of this microcomputer must be set to disabled status.
