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. Brad Circle M ----------
