Dear Marcus,\ \ Thank you for your reply. I think your RF engineers have an aim to have the pads on the PCB for bypassing the switches. In other case, why do you have these pads if they haven't tested if they are working ? Is it possible if you could ask your RF engineers which component values we need to locate on these pads ?\ \ 50-54 dB TX/RX isolation is very low as a dynamic range of many applications. For our application, this is our main problem. That is why we want to try to bypass and see if the isolation of the card increases. There is no data about the TX/RX isolation of AD9364 in its datasheet. There is some information in the forums indicating that the TX1/RX1 isolation is measured as 65 dB.\ \ <https://ez.analog.com/rf/wide-band-rf-transceivers/design-support/f/q-a/79257/ad9361-tx-rx-isolation>
