Re: [Amps] HV MOSFETs for RF

["Leigh Turner" <invertech@frontierisp.net.au>]

Good point Peter; not an appealing scenario for your average punter...where
pragmatism and practicality rule the day.

Perhaps limiting the Class-A PEP to 10 Watts and having a PA bias mode
switch would be a good compromise for keeping the purists happy.

I think there's an unwarranted obsession with low transmitter IMD numbers in
the non-channelized HF ham bands where above a certain respectable number no
practical advantage is realized. In many cases poor Tx signals heard on air
are attributed to bad operator practice and maladjustment rather than
inherent transceiver design issues in respect of IMD; although a few
notoriously bad rigs are out there.

Its not that simple.
My class A amp does 25W and consumes 280W continuously.
Who would buy a K3 then?

##  + 40 dbm  = 10 watts.  10 watts in Class A  would be the simplest way to
achieve low IMD products. 
Perhaps Elecraft should think of doing just that with their K3 series of
xcvrs.
