I just received my ADRV9364. I noticed that people directly connect TXA to RXA and TXB to RXB to make a on-board loop, for example, in this ADI video Getting Started with PicoZed Software Defined Radio (SDR).
I have checked the datasheet. The max safety input power is 2.5 dBm but the output power can be 8 dBm on TX ports. Is it safe to connect them directly?
Thank you very much.
