My customer is testing the performance of ADL5350 in the conditions as below

    -RF freq : 2487MHz

    -IF freq : 2352.5MHz

    -LO freq : 134.5MHz(+6dBm)

    -Signal  : LTE


The conversion loss of ADL5350 was very poor compared to specification in datasheet.

    -Conversion loss in datasheet : 6.8 dB

    -Measured conversion loss : 15dB

It is the particular application but the conversion loss degradation is lowered too much.

Please, let us know how to improve the conversion loss of ADL5350.


Thanks in advance.
