Hi,
I'm looking for a simple way (formulas or software) to calculate pi filters in a final (PA-HF) to operate in a given frequency and in general how to calculate final power amplifier.

hi ... it depends what you want to calculate .. pi -l network depends on many other things .. e.g. class of operation (a, ab, c, ...), tube or solid state?, if tube .. gg(grounded grid) ... good tutorial is on arrl handbook, try to look there or i can post you some papers ... there are many mnfgr out there acom is one of them, other are e.g. eto power/alpha, qro technologies, commander, kendwood, yaesu, icom, henry, ... or many homemade ;0)
