routes between the STM32W and the balun. ST recommends the use of an 0603 inductor to
allow ample space for the traces to go to the balun first with deterministic lengths. Trace
inductance between the inductor and balun is then absorbed into the total shunt inductance,
so it may be predictably offset by reducing the physical component value. The tuned value
on the reference design came out to be 3.3 nH.
Figure 4.
The PCB designer has the option to route the traces to the inductor first and the balun
second, but this has the effect of moving the components further away from the STM32W.
