Problem with AGC in Locosto

Hi guys,

Any people using locosto ?
I met a problem about AGC, Locosto has AFE and ABE gain
calibration in DRP using -60dBm. I found RX level or RSSI had
20dB around drop for all bands. And the drop level is different
when you go in the way of higher input RX power or back to lower
input RX power, quite weird to me. It's a pity locosto is very
intergrated and not much information let user to know, therefore
I have not much idea of this. Could anybody helps ?

Thanks

Wilson

Locosto is so new to the market that I think you are going to have to get help from TI directly. I've seen a lot of papers published in IEEE publications about TI's DRF processor, perhaps you can get some help from these.
