PCB Land Pattern and Antenna Keep-out for BL600-SA
Dimensions in mm.
APPLICATION NOTES
1.
“
RF Out” on pin30 is for BL600-ST only. BL600-ST brings out the RF on trace pad (pin 30) and this
MUST be tracked with a 50-Ohms RF transmission line (preferably GCPW) on the customers host PCB.
More details in section
50-Ohms RF trace on Host PCB for BL600-ST.
2.
Ensure there is no copper in the antenna ‘keep out area’ on any layers of the host PCB. Also keep all
mounting hardware or any metal clear (Refer to
) on of the area to reduce effects of proximity
detuning the antenna and to help antenna radiate properly.
3. For BL600-SA (has on-board chip antenna) best antenna performance, the module BL600-SA MUST be
placed on the edge of the host PCB and preferably in the corner with the antenna facing the corner.
Above “Keep Out Area” is the module placed in corner of PCB. If BL600-SA is not placed in corner
but on edge of host PCB, the antenna “Keep Out Area” is extended (see Note4).
4. BL600 development board has BL600-SA placed on the edge of the PCB board (and not in corner) for
that the Antenna keep out area is extended down to the corner of the development board, see section
PCB Layout on Host PCB for BL600-SA
Figure10. This was used for module development and antenna
performance evaluation.
5. Ensure no exposed copper under module on host PCB.
6. The user may modify the PCB land pattern dimensions based on their experience and / or process
capability.
