The Beidou_3 module, developed by Chengdu Beidou Xingyun Technology Company, is a shielding - enclosure - structured module designed to support the Beidou Radio Determination Satellite Service (RDSS). Internally, it integrates a Low Noise Amplifier (LNA), a high - performance RDSS radio frequency transceiver chip, a 5W - output - power power amplifier module, and a dedicated Beidou RDSS baseband circuit. This integration empowers it to fully execute RDSS positioning and communication functions.This product offers exceptional usability, characterized by its high - level integration, compact form factor, low power consumption, and robust reliability. It is highly versatile and can be extensively deployed across a wide range of Beidou RDSS navigation terminals, including vehicle - mounted, handheld, and data - transmission types of Beidou RDSS terminal devices.

Features:
The module has built-in LNA to filter the RDSS satellite signal, low noise amplification, and the user does not need to set an external LNA, and directly connects to the passive antenna;
The host computer can upgrade the software version of the RDSS function through the serial port;
Built-in 5W power amplifier module, no need to add PA for satellite communication;
The module size is 30×35×3.5mm;
Stamp encapsulation form of SMD;
