It is worse than that, Wes. I fail to understand how a device can be
specified as X dB into a capacitive load. Last time I looked, a capacitive
load couldn't dissipate ANY power.

This is pretty good, but errs when it states that 0 dBm is 1 mW in a
50 ohm system. This is the usual case, but it could just as well be
70 ohm, 600 ohm or 6 3/8 ohm.
