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?
