I am designing a PCB for Zwave Gateway controller and using EFR32ZG14
In datasheet dual matching filter recommendation is Murata LFD21868MMF5E233
But it is not available with any supplier Also we are not able to procure from Murata as well (Mouser, digikey and similar also pulled out)
I found an alternative part with similar specs LFD21891MMF3D931
All specs are matching except
1. ANT Port V.S.W.R in Tx BW = 1.52 MAx instead of 2.1 Max
2. Insertion Lossin BW is also different
So can we confirm the usage LFD21891MMF3D931 for best design or request to please suggest an alternative for the same
