Re: gEDA-user: OFF: capacitors for RF power amplifier

I'm currently designing a power amplifier for the HF (3-30MHz) radio
band.

I am selecting capacitors for the low pass harmonic filter bank at the output.
My question is what kind of capacitors should I use? I apply not more then
100V of say 30MHz maximum.

My best bet is to use X7R capacitors with as much DC voltage rating as I can
get. I don't know if there's any connection between the DC and AC losses.


Thanks,
Levente


I also would recommend the plastic types. Wima makes nice ones but there are others.

C0G/NP0 good too, as already pointed out.
