[hpsdr] Munin Capacitors

[Tony Hagen]

Hi,

Yes, I will replace the caps with the recommended part #.

Hi Tony,

I would be quite concerned about the ability of 1 kV disc ceramic caps to
handle the high RF currents in this part of the PA circuit.

Hi Tony.

Using disc ceramics in the output of a PA is not adviceable. First, they
MUST be C0G or NP0. And even very short leads are negative. So I?ll
strongly advice to use only ceramic NP0 SMD capacitors with >500V ratings.
So far, I have not had any problems with the Munin PA?s I have built and
used.

But I wrongly stated 200V rating for them in the original BOM. Sorry for
that!

Season greetings to all of the Munin builders and the rest of the
OpenHPSDR followers!
