Hi everyone, I’m new to PCB design and this is my first time using KiCad. I’ve designed a simple band-pass filter circuit and created a PCB for it, but I’d really appreciate some feedback from more experienced users to make sure everything is correct and complete.

 

hi iL22.
Please post a circuit diagram, so that we can fully check the layout of your PCB.

Please check the pinout on the BNC connectors. Something seems wrong. The signal and grounds are on different pins.

Also, what is the frequency response of the filter?

 

check pinout for those BNCs. normally the center pin is signal and all others are GND
