STM32WB55V* MLPF-WB55-02E3 or MLPF-WB55-01E3 matching network for UFBGA129

[MSton.1]

Hello STM32-Team,

do i have to use the MLPF-WB55-02E3 or MLPF-WB55-01E3 matching network for UFBGA129. In the Appnote AN5165 (Table 6) the matching network MLPF-WB55-01E3 matching network is recommended, but in the Datasheet of the MLPF-WB55-01E3 its only for the STM32WB55Cx/Rx. In the MLPF-WB55-02E3 datasheet its for the STM32WB55Vx and the UFBGA129 would be the STM32WB55Vx.

So im a bit confused whats the right choice for the UFBGA129.

Thanks an Greetings,

Matthias

Are there any updates on my question? Any additional informations needed?

MLPF-WB55-01E3 must be used for ALL the QFNxx packages for all the STM32WBxx family.

MLPF-WB55-02E3 must be used for ALL the WLCPxx and BGAxx packages for all the STM32WBxx family.

Note that MLPF-WB55-02E3 is a bumpless version.

we now recommend to use the bump version: MPLF-WB55-02D3.

The bump version is less sensitive to board layout and offers a better rejection of harmonics.

MPLF-WB55-02D3 has also been designed for WLCSP et BGA packages and is now in production.

Due to the bumpless characteristic, the MLPF-WB55-02E3 IPD may be more sensitive to the board characteristics.

Hello Remi,

Thanks for the reply so it's wrong in the AN5165.

Is it MLPF-WB55-02D3 or MPLF-WB55-02D3?

Do you know when the bump version will be aviable? At the moment i can't find anything for the PN MLPF-WB55-02D3 or MPLF-WB55-02D3.

Greetings,

Matthias

It is MLPF-WB55-02D3. MLPF stands for Matched Low Pass Filter.

I have a preliminary version of the data brief of this IPD.

I need to check whether I can post it on this forum.

I will look for the PN.

[Remi QUINTIN]

If fact the PN is MLPF-WB-02D3 (55 was removed)

I join the datasheet below.
