• Filter and blocking capacitors should be placed directly in the tracks without stubs, to
achieve the best effect.
• Antenna matching elements should be placed close to the antenna / connector, blocking
capacitors close to the module.
• Ground connections for the module and the capacitors should be kept as short as possible
and with at least one separate through hole connection to the ground layer.
• ESD protection elements should be placed as close as possible to the exposed areas.
