ADL5205 Gain

Hello,

I am testing the ADL5205 using SPI and when I set the gain of both stages to 26 dB, the second stage only amplifies by around 8dB. If I set the first stage to 0 dB, then the second stage amplifies at 26 dB correctly. It appears that the ADL5205 cannot amplify by more than around 20 dB on both stages at the same time. I have also tested three different chips and they all act the same.

 

Has anyone else noticed problems with amplification of the ADL5205?
