this is one of my questions of [LimeSDR mini RF receive front end?](https://discourse.myriadrf.org/t/limesdr-mini-rf-receive-front-end/7560)

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](https://github.com/myriadrf/LimeSuite/blob/master/src/lms7002m_mcu/MCU_BD.cpp#L1039)  
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,  
hayati
