Please clarify below things of AD936X Tx/Rx BB LPF functionality.
For an example my RF Bandwidth is: 1 MHz and real bandwidth of Tx BBF and Rx BBF could be 500 KHz .
1. How to calculate the 3 dB frequency of each filters? i observed in few documents you mentioned the 3 dB frequency of above example 0.7 MHz for Rx BB filter and 0.8 MHz for Tx BB filetr. could please explain more like how to calculate the 3 dB frequency for required bandwidths.
Please explain what is the function of ceil function in this formula. It will be better if you explain with one example.
Thanks for your support
