868Mhz ASK Wireless Transmitter Module DL-TXS868T
Product Description
868Mhz High-performance ASK Wireless Transmitter Module
DL-TXS868T wireless module is a low cost, high performance and good stability RF transmitter module. Designed base on a brand chip, it is a high-performance ASK Transmit Module for RKE (Remote Keyless Entry) system. It includes a SAW oscillator and a Power Amplifier controller. The output power reaches 10dBm at 3.3V, with fewer peripheral components, it has a stable frequency and debugging-free, operating in 450~1000MHz frequency range, wide voltage ranges from 2.5V to 3.6V, which is very good for battery power supply systems, such as remote control, wall switch, etc.
It has high output power (max:10.5dBm) and transmission rate (10Kbps). With good harmonic suppression, the second harmonic in maximum power output mode is less than -35dBm, which meets the European RTTE certification standard of 868.35MHz. This product can be widely used in automatic remote-control chip lock, keyless entry system, wireless home security, wireless remote-control system and wireless smoke detector related products.
Features
● Operation frequency: 450~1000MHz (default frequency: 868.35MHz);
● Transmission distance: 300 meters in an open air; 10dbm@3.3V;
● Operating voltage range: 2.5V-3.6V;
● The DATA input port uses a single-end serial port.
● Harmonic suppression ensures that it is certified by FCC, RTTE, etc.
● The module is compact in size, and has no adjustable elements on the periphery, so it is easy to use.
● Can be directly SMT on the remote-control products.
