CC1310: Maximum RF Input Power System Workarounds

$

Part Number:CC1310

Hi,

Background

The maximum input RF level of the CC1310 is specified as 10dBm in Table 5.1 of the datasheet. A system being developed with the CC1310 will have two devices near to one another and a CC1190 is being considered for use to extend the range of the overall network which may result in higher RF levels being seen on the non-transmitting device due to their physical proximity.

Question

  1. Does the maximum input RF level only apply while in RX mode, or at any time? Specifically, could the device be taken out of receive and safely handle higher RF power on the input path?
  2. Is the input RF level specification dependent upon which frequency the device is currently tuned or is any frequency able to damage the device assuming a 10dBm RF level is seen on the input?
  3. Are there any recommended system-level solutions for addressing this type of problem?

Best Regards,

Mark-
