SA618F30-DZ : 1W 8 Dual Antenna Multi-Level Relay 8K Sampling Rate Audio Module Full-Duplex With ESD Protection

  • The SA618F30-DZ is based on our company's SA618F30 module, with a design that separates the transmission and reception antennas. Additionally, the TXEN pin is externally extended, making it more convenient for customers to add an external radio frequency power amplifier. This allows for higher transmission power and enhanced communication distance. The module integrates a high-speed microcontroller, high-performance RF transceiver chip, and RF power amplifier. It also provides a standard serial port for communication with the module, enabling easy and quick setting of relevant parameters and control of the transceiving functions. By simply connecting an audio amplifier, microphone, and speaker to this module, it can function as a compact walkie-talkie. The simplified interface and ultra-small size of the module allow for its wide application and easy integration into various handheld devices, thereby improving the overall performance of the end product.
  • The SA618F30-DZ is strictly manufactured and tested using lead-free processes, complying with RoHS and Reach standards.
