Question

STM32WL55 RFO_HP signal line overlapping VR_PA signal line on different PCB layers

Hi, am working on a STM32WL55 solution that has both Hi power (RFO_HP) and Low power (RFO_LP) circuitry included (like that of the WL55 Nucleo PCB, either one of which is used at a time). Am at a component placement situation where the VR_PA signal line has to physically cross over RFO_HP signal line but on different layers. Would it be advisable to route the VR_PA connection from the feedback noise filter network on a separate layer cutting across the RFO_HP line, in perpendicular to each other? Components are only on one side of the board as overall finish has this limitation. Thank you.
