4.4 RF PCB Design
4.4.1 Antenna RF Connector
The two-way antenna of L610 module adopts the pad-out way. It is recommended that clients use the
U.FL-R-SMT-1 antenna connector and the matching RF adapter cable.
The antenna is a sensitive device and is easily affected by the external environment. For example, the
position of the antenna, the space it occupies, and the surrounding ground all may affect antenna
performance. In addition, the RF cable connecting the antenna, and the position of the fixed antenna also
may affect antenna performance.
Figure 4-1 is the reference circuit design for the main and diversity antenna. These matches need to be
placed close to the antenna:
