I'm comparing two parts, the AD8302 and the ADL5519. The AD8302 datasheet discusses the envelope bandwidth quite a bit, and specifies it at 30MHz, while the ADL5519 only has a spec of 10MHz. Is there a reason the ADL5519 has a lower envelope bandwidth than the AD8302. Is there any way to increase this? Does ADI have any similar parts with a higher envelope bandwidth?
