What Features Should a Portable Walkie-Talkie Module Have? Take G-NiceRF SA828 for An Example
Due to its compact and lightweight nature, Portable Walkie-Talkie Modules are widely used in outdoor activities and scenarios that involve frequent movement. Meanwhile, outdoor communication demands certain requirements for communication distance and anti-interference capability. The balance between transmission power and power consumption of walkie-talkie modules tests the design capability of the module's functionalities. Excessive functional requirements may lead to uncontrollable module size, thus necessitating high-integration circuit design to ensure stable and clear communication connections over long distances. Low-power design not only effectively extends battery life but also reduces heat emission, contributing to device stability.
The SA828 high-integration walkie-talkie module is a cost-effective communication solution. It features a high-speed microcontroller, a high-performance RF transceiver chip, and an RF power amplifier built-in. G-NiceRF's PC software allows for easy and quick configuration of parameters such as squelch, transmit/receive frequency, and noise level. Users only need to connect an external power supply, speaker, and audio potentiometer to this module to create a small walkie-talkie with 16 adjustable frequency channels. Its simplified interface and ultra-compact size enable widespread application and easy integration into various handheld devices, enhancing the overall performance of end products. The SA828 module is strictly produced and tested using lead-free processes, conforming to RoHS and Reach standards.
Highly integrated with a compact form factor, the SA828 features a high-speed microcontroller, a high-performance RF transceiver chip, and an RF power amplifier built-in. Users simply need to connect an external power supply, speaker, and audio potentiometer to turn this module into a small walkie-talkie with 16 adjustable frequency channels.
High Reception Sensitivity for Long-distance Transmission
High sensitivity enables receiving devices to better capture and decode weaker signals, reducing the likelihood of signal loss or distortion and improving communication quality and stability. Generally, if the receiving sensitivity of a device is higher at the same communication distance, the transmission power of the transmitting end can be correspondingly reduced.
Transmitting and Receiving Frequencies Are Independent
The SA828 boasts a high sensitivity of up to -124 dBm, allowing receiving devices to capture and decode signals from long distances, achieving a transmission range of up to 4-5 kilometers. Additionally, considering power consumption, the SA828 provides a sleep function. The sleep current is less than 3μA, significantly extending the working time of the walkie-talkie, and meeting outdoor work requirements.
Transmitting and receiving frequencies are independent" means that the frequencies used by communication devices for sending and receiving data are mutually exclusive. This implies that sending and receiving operations can occur on different frequencies without interfering with each other or being restricted. For example, in wireless communication, if the transmit and receive frequencies are not independent, when a device transmits a signal on a certain frequency, it may interfere with the reception operations of other devices on the same frequency. By ensuring the independence of frequencies, such interference can be avoided, thereby improving the quality and efficiency of communication.
Can Pass the EU CE Certification
The SA828 intercom module can be equipped with the SA818S module, which has obtained the EU CE certification. CE certification is a unified recognition mark of the European Union for product safety, environmental protection, and other aspects. If your product is to enter the European market, it needs to comply with the relevant requirements of CE certification. This indicates that the product meets the basic requirements of the EU Directive on Technical Coordination and Standardization, which is a mandatory requirement under EU law for products.
In conclusion, the SA828 is a highly integrated long-range intercom module. In addition to the high integration and long-distance transmission described above, power consumption is also taken into consideration. Low receive current and sleep mode are also suitable for outdoor work. This product sharing ends here, and G-NiceRF will continue to adhere to product innovation, creating more value for G-NiceRF customers.
