Re: ATU-10: an alternative PCB layout?


 

Hi, everyone. I'm BI6MPW from China. I may have found some problems in the process of learning and making atu10.

When I studied this version of PCB of zao, I found a doubt that could not be ignored, which may cause the colleagues who have assembled this version of kit to fail to run it correctly.
?
In lay6 file, the output RTX solder pad of swr bridge is connected to gnd, which will cause the two stages of RF signal to be directly short-circuited here, or can you give me some tips, whether the design here is reasonable?
?
I thought I could modify it to be ungrounded and draw two patch pads near it, so that even if my attempt failed, I could restore it to its original condition
?
Any help is useful, please make suggestions
