Other Parts Discussed in Thread: AFE031
Hi,
we're currently struggling some issue with AFE032. On some of our boards we have problem that after receiving first few packets our PA Output going down, we see short circuit to GND on PA Output and AFE032 internal temperature reaches about 100 Celsius without sending any data. Receiver works still fine but we cannot send any data because PA Output didn't send anything. What may cause such problem?
We're supplying AFE032 with 18V DC and our coupling circuit looks like this:
We're using external DAC from MCU.
