AGC loop using AD8318 and ADL5330

Category: Hardware
Product Number: AD8318 ADL5330

I want to design an AGC loop as described in datasheet of the ADL5330.

I have two questions:

1-) AGC loops need a VGA, a detector and a comparator. As can be seen from the datasheet, there is no comparator to be used for AGC loop.

Is it only populating ADL5330 and AD8318 enough to construct an AGC loop?

2-) Bandwidth of the AD8318 is very wide which is from 1MHz to 8GHz.

But I want to only measure 20MHz bandwidth around 1.5GHz.

Is there a setting for AD8318 to adjust its bandwidth since I do not want to use additional SAW filters?
