main features

RDF900A is a wireless data transmission module with small volume and excellent performance. The main features are:

1. Regardless of transceiver design. each module is integrated with USB serial port chip. and USB and UART interfaces are automatically switched. USB takes precedence

2. Operating frequency range: 902-928 MHz. ISM band

3. The transmitting circuit is designed with a low-noise amplifier greater than 20DB. and a low-pass filter unit is added

4. The transmission power is adjustable. Maximum 1W transmit power

5. High sensitivity LNA and SAW circuits in front of receiving circuit

6. The outdoor communication distance can reach 40 km or more in a straight line (depending on antenna performance and communication rate requirements)

7. The air data rate can reach up to 250Kbps

8. Dual antenna interface. supporting antenna diversity and differentiated antenna configuration

9. Support AT command configuration of local radio station and RT command configuration of remote radio station

10. It has module temperature monitoring function and automatically adjusts the duty cycle according to the temperature to avoid overheating

11. Working temperature – 40 to + 85 ℃
