INTRODUCTION
This guide gives recommendations how to design electronics around WT11-A module.
Although the module has an integrated antenna there are still things that can go wrong.
It’s strongly advised to treat RF with respect to achieve the best performance possible.
Careless electronics design can result in EMC problems and a deteriorated performance.
An awareness of the EMC design of a product is the only way to guarantee disturbance
resistant products.
A day spent at the beginning of the project preventing EMC problems can save a
month of fixing problems at the end.
Following chapters give several recommendations how to do a good design. Nevertheless,
a designer should never copy and paste a reference design and expect it to work. In the
world of RF nothing is certain. A situation varies from design to design. So the designer
should always stop to think. Do not trust on luck. It is a certain way to encounter
problems.
