Excessive TX-RX Coupling or Reflection can Lead to Saturated RX Output

Revision(s) Affected:

AWR1843AOP ES1.0

Description:

If there is excessing TX-RX coupling or chassis reflection, it can lead to a saturated RX output. This situation can occur if the RX input is stronger than -10dBm.

Workaround(s):

Improve TX-to-RX antenna isolation on PCB. Radome/chassis should give low reflection amplitude and should be as close as possible to the sensor, to reduce the IF frequency.
