for PVDD decoupling capacitor is it required 330uF capacitor for 2 to 3W amplifier output? can we go with low value capacitor?

Hi Amit,

You should be able to go to 100uF for only 2 or 3Watt.

also can you please confirm output inductor we should use 22uF coupled inductor only or can we go with two different 22uH inductor in series with OutP and OutN

Amit,

You cannot use a coupled inductor. The 22uH inductor on the EVM is not coupled, but two inductors in one package for smaller size. Since you are running low power, you can probably use 15uH and a 1uF capacitor to ground. The 15uH can be a smaller size since the current is much lower.
