Hi


I'm  prototyping with a single-ended circuit configuration (Datasheet P 14 Fig. 41) using the evaluation board of the AD8351.
Although a differential output is measured by inputting a 1Vpp sinusoidal wave (50 kHz to 200 MHz), the amplitudes of Hi and Lo are different.And the gain setting is used at about 6dB, the OPHI gain lowers around 100MHz.


I want to flatten gain up to about 200MHz.




Thank you.
