RF-BM-BG22B1 www.szrfstar.com 4.3 Antenna 4.3.1 Antenna Design Recommendation 1. The antenna installation structure has a great influence on the module performance. It is necessary to ensure the antenna is exposed and preferably vertically upward. When the module is installed inside of the case, a high-quality antenna extension wire can be used to extend the antenna to the outside of the case. 2.
RF-BM-BG22B1 www.szrfstar.com which is beneficial to the long-term stable operation of the whole machine. The module should be far away from the power electromagnetic, transformer, high-frequency wiring, and other parts with large electromagnetic interference. 4. The bottom of the module should avoid high-frequency digital routing, high-frequency analog routing, and power routing.
RF-BM-BG22B1 www.szrfstar.com 4.5.2 Vulnerable Module 1. Please ensure the supply voltage is between the recommended values. The module will be permanently damaged if the voltage exceeds the maximum value. Please ensure a stable power supply and no frequently fluctuated voltage. 2. Please ensure the anti-static installation and the electrostatic sensitivity of high-frequency devices. 3. Due to some humidity-sensitive components, please ensure suitable humidity during installation and application.
