Application note

Antenna desense on handheld equipment

Introduction

Mobile applications such as phones or tablets feature high-speed links to provide video with

high definition or high data rate storage. The antennas used by the equipment to

communicate with the base station become more and more wide band or smart, so are

more sensitive to electro-magnetic interferences.

We will show in this note how the receiver sensitivity can be affected by this noise and how

it is possible to maintain a correct reception.
