I'm seeing only -26 dBm output power from the ADRV9361-Z7035 at 6 GHz, and around -15 dBm at 100 MHz.
I'm using a simple GNU Radio FMComms2/3/4 sink with a constant source.
With max hold on the analyser at 6 GHz I get up to -18 dBm during startup, before it falls back to -26 dBm. There is 0 dB TX attenuation applied, and I am using the supplied U.FL to SMA adapter cable.
Changed Z035 to Z7035
