1. What is the default value set for these two in WARPLAB reference design examples?
2. From the data sheet, rx_lpf has 4 possible arguments 0 1 2 3 corresponding to frequency band 15 19 28 36
on the other hand, tx_lpf has only 3 possible arguments 1 2 3 corresponding to frequency band 24 36 48
They are actually not the same for the same arguments. For example, if I set 1 for both rx_lpf_corn_freq and tx_lpf_corn_freq, then the transmitting frequency is 24MHz while the receiving bandwidth is 19MHz? It's weird.

Thanks. So the default value is tx@24MHz and rx@19MHz.
If I use WARP to receive a standard 20MHz signal, I will miss sone of the signal because the receiver is only listening on 19MHz bandwidth? Am I right?

You can find the default values for those parameters in the ifc_init function.

The Rx LPF response is specified in the MAX2829 datasheet ("Rx BB Frequency Response" on pg 23). The register settings describe the 3dB point of the response.
