Hi, Lou. My experience with RF circuitry is that RF circuits tend to be
significantly less dense than digital or analog circuits. Hopefully this
allows you to use larger passives.
On 0201s - Kemet reps have indicated they will begin production of
0201 caps sometime next year. I do not know anybody that is planning
to use them. There's very little reward for shrinking from 0402s to 0201s.
