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?
