So seeing as the Mini on has 1 SMA connector which of the 3 antenna setting should I use to actually use it.

Low  
High  
or  
Wide

RX1\_W (wide) and RX1\_H (high) are connected through matching networks. RX1\_L is not connected but command is allowed (effect is like antenna is disconnected).

Is there any docs of what filters on those two paths?

Is it like the normal LimeSDR with annoying filter I have to play with to get the full range at a good sensitivity out of the device?

Also any idea about on Transmit?

Hey look finally have 4 months that page has use-full information. (It use to have TBD in that section)

Thanks. That doesn’t answer the question of if I have to deal with balun in place not designed for those ranges. (Like on the full LimeSDR)
