We are using your DVGA part ADL5240 for our 1GHz application at Below input levels.
Maximum Input Power to AMPIN: +14.5dBm (where as Absolute MAX in datasheet is +16 dBm)
Operating Frequency : 1 GHz
Supply : +5 V @ 93 mA
We are facing random this DVGA failure in our module ( 2 times) without exceeding any of datasheet absolute maximum ranges.
After failure DVGA ( AMP gain reduced by 40dB) we checked drain current of Amplifier using series DCR and it is around 15mA only.
Since this a second random failure in our total 10 nos of assembled module ( only two got failed )
We have attached DVGA section Schematics for your reference.
Kindly provide suspected root cause for the failure of DVGA and suggest a solution to resolve the issue to proceed further.
