This is beginning to line up.?
3.5 volts at 300 kHz,
3.5 volts across a 40 ohm resistor = 87.5 mA,
87.5 mA divided by 23 mA/GHz = 3.804 GHz,
Right in the correct 1-6 MHz high stated range.?

It's a straight line, so pick any frequency you want. There is a non-linearity starting above 5.5 GHz or so. But, you are having problems at the low end, below 1 GHz rf out. That means the YTO is tuned to ~4.8 GHz when the rf output is 1 GHz.. Let's say you pick 4 GHz as a test point. The current should be 4 x 23 = 92 mA. If the actual coil sensitivity is at the upper limit (24 mA/GHz), then 96 mA.
