Hi Marcus,
Thanks for your quick response. I still have some doubt. In X410 spec, there is
clear information on max input rf power: +14dBm for f<3GHz, +17dBm for f>3GHz

Just to follow on. The BasicRx is +10 dBm. I've been using that as a max to
the BasicRx for quite a while without issue. But the UBX-160 knowledge base
indicates -15 dBm. I'd assume if you're using the UBX that you'll be using
the configurable on-board amplification (up to 31.5 dB).

Also notice that the input power to the X310 (the ADC described
in the first link) might not be relevant to the UBX-160 daughter board
input with its preamplifier and mixer or RF frontend in general.
With a BasicRX (ie balun -> ADC direct connection, no frontend/mixer/preamp)
I have measured the
