Hello Dmitriy,Concerning the line before the filter (RF in I/O) for MLPF-WB55-01E3 , for routing/spacing reason this line cannot be sufficiently wide to be 50 ohms.Width has been chosen to allow proper routing while length has been minimized to allow...

Hello, please find below answers to your questions :1/ Yes this line is 50 ohms impedance , this line is CPWG referenced to layer 2 in order to have a narrow line to allow proper routing up to the STM32WB. This line must be 1.5mm length.2 / You have ...

Hello, concerning your point 1/ for the line between MLPF and antenna, you have to consider reference ground plane in layer 3 and not layer 2 (see fig 13). So H must be set to 1303um which will lead to a 50 ohms impedance.for point 2, yes the line ...
