Actually, I was wrong in previous EMail:
here is 10 Wt bi-directinal Amp - just found it
http://www.hyperlinktech.com/web/ha2410.php
I did not see it 1 year ago. I guess world is getting better ....

it is expensive though

Hi all,

Any suggestions? Thinking in terms of maybe 10W out / 200mW in or
thereabouts.

Thanks,

p.

It is rather! I wonder how much the internal components cost?? The
site seems a bit short on technical info on these amps. What do they
mean by "bi-directional"? If they're talking about some sort of RX
preamp feature built in, it ain't gonna be 10W surely! :-)

It is exacty that: PA from Input to Output and LNA another way. Otherwise
you can not run the Network.

And this one does look like 10Wt - judging by the size of the heatsink

It does look rather *large* for 10W, I guess. But is this due to the
frequency of operation? I mean, presumably efficiency drops off as one
goes up in frequency so maybe the PA is dissipating more heat than an
equivalent PA operating at, say, 430Mhz?
