6 Design Guidelines

6.1 Recommended PCB Footprint

All dimensions in Figure 3 are in thousands of an inch unless otherwise marked.

Figure 3. AMS00x Recommended Footprint (Top)

6.2 Routing Recommendations

When designing a carrier board, the addition of

ground fill directly underneath the module, rather

than signal or power traces, is strongly advised.

All ground pads adjacent to antenna pins must be

connected to a solid ground plane. Do not route

ANY metal or PCB traces underneath the printed

PCB-antenna!

Failure to comply with these recommendations will

almost certainly result in degraded performance of

the radio receiver and/or transmitter.

For optimal range, provide a clearance of 5mm

(0.2”) above, below and to the front and sides of the

antenna end of the module.

Avoid routing traces not connected to ground under the

vias in the shaded rectangle.

Measurements are in thousandths of an inch.
