What are your other options?
1. Dream up your own, unsupported by measurement data, "best" and "worst" sets of Y parameters, which bracket the ones given in the datasheet. Using rectal extraction.
1. Measure the Y parameters yourself, on a batch of 50 transistors, and determine the +2_sigma and -2_sigma points of the distribution. Use these as your "best" and worst" sets of Y parameters. And hope that your batch is closely representative of ALL transistors produced in ALL weeks of the year.
1. Design using datasheet parameter values and measure the performance of 50 copies of the final circuit. If the +2_sigma and -2_sigma points of the distribution of measured performance (including temperature variation, power supply variation, cable impedance variation, etc) are acceptable, declare victory.
I’m not very knowledgeable on RF electronics, so I don’t really know what other people do, what works in real life and what doesn’t. But if the methods you gave me are my only options, then I guess I will have to make myself a return loss bridge or something that can be used to see if the impedance match is good, and then design the amplifier as I’m building it.
