alternative of ad633

forgot about it, where I can find schematics using HBT's for higher bandwidth for this purpose?

Do you want it for electronic load?

I think such chip is very expansive.

Can I use it in modulation? It is a multiplier right?

CV104

use amp to diy it

I got one Burr-Brown MPY634 analog multiplier but for ranges I am going to use it is fine, or seems fine to me.

thank you.
