The evalboard has been optimized for 3V. The load is about 250+j0 at 915MHz.
A tuning-free realization requires a careful design of the components within the matching network.
A simple linear CAE-tool will help to see the influence of tolerances of matching components.
Suppression of spurious harmonics may require some additional filtering within the antenna
matching circuit. Both can be seen in Figure 3-9 and Figure 3-10 The total spectrum of the
evalboard can be summarized as:
