Figure 4: Test set-up
3.1 RF trace PCB routing
The PCB routing connecting the module’s antenna pins to module board U.FL connectors are
designed with coplanar microstrips. Coplanar microstrips are also used on the carrier board
connecting the U.FL connectors with the SMA connectors to which the external antennas or test
equipment are connected. Figure 5 and Table 12 shows the design stack-up including
dimensions of the 50 Ω coplanar microstrips implemented.
Regarding the coplanar microstrips the ground planes beside the signal trace are connected to
the inner layer ground plane using vias. The vias are placed with a maximum distance of 0.5 mm
to the coplanar ground edge and a maximum pitch of 2 mm. The top layer is coated with
generic LPI solder stop mask.
The SMA connectors on the carrier board are used for mounting antennas. For Bluetooth and
Wi-Fi operation in the 2.4 GHz band and Wi-Fi operation in the 5 GHz band, the module has
been tested and approved for use with antennas up to 2 dBi antenna gain.
