Here be a lesson to all, never throw away old data books that contain potentially useful information and just rely on being able to down load it again at any time.
It is hard enough trying to read the impedances from the original let alone a pdf of a scan.
As near as I get estimate the input impedance at 200MHz is 4 - j15 ohms and the output is 160 - j35 ohms.
What it will be at 150MHz you will have to estimate yourself. Allow some tuning I would guess that a 2N3866 made now will not be like one made when that data was taken. About all you can say is the impedances will likely be in roughly the same part of the chart and follow a similar path.

E-design has a better old data book than I have; I've got an old RF databook at nome, but here I've only got the small signal transistor book from 1983. The smith chart in that is tiny, I needed to use a microsope to try to read it. I read it in a bit of a hurry and had difficulty getting the book postitioned so I could read it, as a consequence I got the real and imaginary parts of the impedance swapped while writing it down.
I found a link to an RCA datasheet that has impedance data to 150MHz

and they are completely different from the Motorola data.
If you can you may well be beter off measuring the device you have. These generic parts can differ markedly from one manufacturer to another, ther eare only a few parameters that are controlled; current gain, ft and maximum voltages are about it. There are number of designs published in the past, particulary for VHF amplifiers that only rarely worked when replicated because of this.

The data I converted into an S2P file was from the RCA data sheet, and the data point you plotted comes close to the same point on the chart as shown in the data sheet.
It is not too difficult to do the same for the Motorola data. Convert the impedance to reflection coefficient and alter the file. It looks like your matching program only uses spot frequencies does not use S21 & S12 so leaving those alone will not affect things much.
My estimate of 150MHz large signal input & output impedances at 150MHz are 4 -j20 and 35 -j200 the reflection coefficients for those impedances are 0.87 -136 and 0.92 -27.

As you can see from the differences between the two manufacturers datasheets if you do not have a Motorola device the circuit may not work too well or need a lot of tuning.
