Hi Tony,
An old Motorola app. note, AR510 covers the SWR topic. It is a
reprint of an article from the February 1991 issue of "RF Design" magazine.
A simple diode level detector should be suitable for the
overdrive/ALC function.
73 & Good morning,

I'm building the EB104 600 watt solid state amp. described in June '06 QST.
I'm concerned about operating into a high (or moderate) SWR, and thought
that an SWR protection circuit would be a useful additon to the amp. Also
an overdrive protection circuit would be nice. Can anyone point me to a
suitable circuit or 2?
Many thanks for any advice and 73,
Tony, N2UN
