I have some questions on the response here:
https://community.st.com/s/global-search/MLPF-WB55-02E3?t=1636577804470
The response references MLPF-WB55-01E3 but I think it should be MLPF-WB55-02E3 for the WLCSP_100 package. Can you confirm the 65 ohm impedance is correct for the MLPF-WB55-02E3 filter?
I am using a different stack-up than the one in the MLPF-WB55-02E3 datasheet. I will implement a 65 ohm CPW for our stack-up. Once that is done is there still a requirement to maintain a trace length of 1.5 mm? Thanks.
