Schematic for the AD9258 looks good. If they seeking better linearity performance, they may consider using another amplifier since ADA4937-1 linearity performance falls off between 120-180 MHz. Perhaps the ADA4939 would provide better linearity…
The question is about the ADA4939-1:
To which voltage level the exposed pad shall be connected?
Fig.53 in the datasheet indicates, that the pad is connected via 5 vias to a burried GND-Layer.
Nowhere else in the datasheet the recommended voltage level…
Hi ADI Enineers :
I intend to use ADA4939-1 to drive AD9484 , DC coupled , ADA4939-1 output 1V Vp-p volatge , AD9484's CML output 1.7V voltage , so ADA4939's positive output will reach to 2.2V , It seems exceed the absolute maxim VIN+ . Could you help…
ADA4938 or ADA4939 in the band 0=500mHz C=some Pf
My customer want to use ADA4939-1 and AD9258-125 at ICS repeater.
They will use 120MSPS Smapling rate and IF band is 90MHz (with 10MHz Bandwidth).
Would you confirm attached schematic with ADA4939-1 and AD9258-125?
And also can this circuit…
Can you send me a schematics of how you plan to connect the ADA4817 with a series resistor between each output so that it looks like a ADA4939?
Can you send me an email at email@example.com?
It will be much easier to discuss there…
