I'm looking for an SMT capacitor that can couple 300W at 144MHz on the output side of an LDMOS bias.
This answer talks about wattage dissipation based on ESR, so I can figure that out; my questions for choosing an RF power cap are about sizing:
What are the typical power ratings for capacitors in the 0402 -- 1206 range?
- There is plenty of documentation for resistor power ratings by SMT size, but couldn't find any for capacitors---are those the same ratings for caps?
Is the DC rating voltage for the capacitor a peak or RMS rating for RF pass-through?
- One side of the cap will have a 50V positive bias, does that affect the DC rating that I need to choose (ie, 50V + V_rms or some such thing)?
Mica vs Ceramic vs other?
Are there other considerations when choosing an RF power cap?
