of a handheld device and adversely
affect its performance. FCC Part 15
sets maximum allowable emission and
immunity levels for all digital devices.

out the undesired frequencies as well as
protecting the port against both positive
and negative ESD voltages. The device
is a 3x2 array flip chip and measures
1.5 x 1.0 x 0.65 mm. The small size
and profile of this device is ideally
suited for portable applications.
