Hello

 

When ADF7023J was emission test, it was symptom similar to latch-up.

Symptoms was SPI communication hang-up too.

In order to return. it power down and restart.

 

Test Condition was below.

ADF7023J was metal shield and add λ/4 rod antenna.

EMI; Using radiation probe 1.5kV apply, distance 5cm, period 5usec.

 

In specification LNA P-1dB is -21dBm.

I watch datasheet, but don't find absolute maximum rating of Rx pin.

 

And I think test condition emission rating was too large.

 

How much rating of emission in Rx(RFIO) pin?

 

Best regards
