The data in this page are to make clear the test condition of impedance matched to next stage, not specify the

recommended condition. The S11 smith charts of the test fixture setting IC are normalized to ZO = 50 Ω, because the

IC's load is the measurement equipment of 50 Ω impedance.

In your use, the output return loss value can be helpful information to adjust your circuit matching to next stage.
