Set Bandwidth question

this is one of my questions of LimeSDR mini RF receive front end?

for a buy - or not question i would expect the answer to be found in a spec or datasheet document per device model!

however, dived into the referenced source of LimeSuite/MCU_BD.cpp at master · myriadrf/LimeSuite · GitHub
thanks @mzs for the links.

i don’t see any bandwidth values for analog filters sitting between antenna and the ADC !?
and “if(param==MCU_REF_CLK || param == MCU_BW)” lets me assume, that just some digital clock is modified … !?
i need more explanation on this. are there any analog filters in front of the ADC?

kind regards,
