Using LPFH and LPFL filters (and perhaps others) to exclude near band interference



According to the LMS7002M datasheet there are two analogue filters in the RX signal path. RXTIA(which is an amplifier and a filter) and RXLPFH or RXLPFL. Although RXLPF controls are on the RBB tab of LimeSuite I can’t find anywhere how to set the cutoff frequency for the RXTIA.

Could someone please explain how RXTIA filtering is tuned, please?

Also, it would be great if the docs had some examples of analogue filtering.
