Using Op Amps for RF Design
Abstract
Op amps have become fast enough that they can now be considered for RF designs, traditionally the domain of discrete transistors. There are many parameters for RF circuit design that are different from those specified with op amps. They are, however, related in ways that are explained. Real sample RF circuits are presented.

19.1. Introduction
RF design used to be the exclusive domain of discrete devices. The advent of new generations of high-speed voltage- and current-feedback op amps has made it possible to use op amps for RF design. Op amp–based RF ...
