iT3022D
10 GHz, 6 dB-Gain Differential Buffer
Description
www.DataSheet4U.com
Features
The iT3022D is a differential buffer amplifier designed for use in applications up to 10 GHz.
It supports fully differential operation as well as single-ended-to-differential and single-
ended-to-single-ended operation. The iT3022D is ideal for any RF application in which a
highly-linear, low-gain differential buffer is required, such as microwave communications,
test equipment, digital receiver systems, front ends for digital sampling oscilloscopes, and
single-ended differential transformers. The amplifier provides excellent linear performance.
AC and DC input coupling are accommodated as well as DC-coupled SCFL differential
inputs.
