Antenna Information
Antenna Type
Antenna can be connected using On-board PCB antenna or an external antenna; the default way is using the On-board PCB antenna. If external antenna needed, please contact BD manager.
Reduce Antenna Interference
While using the On-board PCB antenna, in order to have the best Wi-Fi performance, it’s recommended to keep a minimum 15mm distance between the antenna part and the other metal pieces.
U.FL RF Connector
Figure 3 shows the physical parameter of the U.FL RF connector.

Note: the tolerance of PCB outline boarder is ±0.15mm, the tolerance of PCB thickness is ±0.1mm
Production Guide
The storage for the delivered module should meet the following condition:
- The anti-moisture bag should be kept in the environment with temperature < 30℃ and humidity < 85% RH.
- The expiration date is 6 months since the dry packaging products was sealed.
Cautions:
- All the operators should wear electrostatic ring in the whole process of production.
- While operating, water and dirt should not have any contact with the modules.
