Joe,
the HP 434A calorimetric power meter does the trick as it works from DC
to 12.4 GHz.
And, it measures 10 mW to 10 W full scale.

Just scroll 2/3 down.

We all have our various highly accurate frequency and perhaps time
references. Is there a relatively simple and inexpensive method of
making an accurate RF power level reference? If so, then what do we
calibrate it with, not already having such an accurate reference?
One possibility that comes to mind is an HP 436A power meter. These
are abundant and usually have no sensor probes (which are expensive).
They also have a built in 50MHz, 0dBm reference. However, without more
fancy test equipment, I have no way to calibrate the reference, or
even verify that it is accurate.
