Re: [Discuss-gnuradio] power amplifier

For a general purpose linear amplifier, it is hard to beat minicircuits.
Just be careful not to overdrive it, they get toasted easily.

I had exactly the same need as you, although I did want a bit more power,
but couldn't find anything "off the shelf". In the end, I went for this:

y.html

Was able to turn it down though, just by driving it less, and (switchable)
attenuators in line. Was running it's VHF brother at about 2.5 Watts just
last week.


Most of the 2.5W-5W output P.A's I found were really aimed at FM handhelds,
so *not* linear.
