The phase noise specifications for an amplifier are meaningless if the input
signal level isnt specified.

The HP K22 had a specified noise figure as <7.5dB (I'm guessing its NF is
not around 1dB) and the measured noise floor -175dBc/Hz at 10kHz and up at
400MHz from the datasheet.
Since I've had a need for a low-gain (2-4dB) isolation amp at the
100-500MHz range, I've experimented with a cascode
