We are having a problem with a radio system where we am experiencing link dropouts. After troubleshooting, we suspect that our signal is too close to the RX filter bandwidth.
My question: How close to the edge of the bandwidth of the RX filter do we start to experience attenuation?
Also, am I interpreting Figure 13 from the CC1120 user guide correctly? My current interpretation is that when you activate feedback to the PLL, the RX filter bandwidth takes a more rectangular shape as opposed to a more rounded shape when its turned off.
