Low pass filter for STM32WB55Vx

[Dmitriy Dmitriy]

The MLPF-WB55-01E3 filter is especially for STM32WB55Cx and STM32WB55Rx. Are there differences STM32WB55Cx, STM32WB55Rx and STM32WB55Vx (WLCSP 100L DIE 495 PITCH 0.4 ) of RF pins impedance? Can I use MLPF-WB55-01E3 for STM32WB55Vx?

[Remi QUINTIN]

Effectively, the RF output impedance for the STM32WB55Cx/STM32WB55Rx devices is different from the one for the STM32WB55Vx.

So, another filter for the STM32WB55Vx with the reference MLPF-WB55-02E3 will be available in a few weeks.

Will it have same pIn-out and package as the MLPF-WB55-01E3?

[Remi QUINTIN]

Yes, it is the same package and the same land pattern for the PCB assembly, only the RF measurements are slightly different.

The datasheet will be available in a few weeks.

Thank you very much!
