(1) Systems with external antenna connector: Margins for passing conducted requirements at sub 1GHz frequencies can be improved by

using a simple band-pass filter connected between matching network and RF connector (1.6 pF in parallel with 1.6 nH); this filter must be

connected to a good RF ground.
