I have to redesign matching for these ports because our layer stackup is different than the one in reference design. I'm worried that I have made a mistake in the design because I cannot get the example design to work.
According to datasheet, RFIN impedance is 22.9-j14.9 but the example (attached) is not even close if I'm calculating it correctly. The subject was touched on this thesis:

https://digikogu.taltech.ee/et/Download/3313a5fa-758e-4084-9453-9cb8f53eef73

where the author says that the example ignores the complex part and uses the real part only but I cannot get it to match even if I ignore the complex part.

Is there a mistake in the datasheet or any other ideas?

I also calculated LO and that actually seems to be a good match but I still cannot understand what is going on with RFIN
