GENERAL DESCRIPTION

The ADCA5191 is a medium power gain block amplifier that provides

excellent linearity across a flexible bias range allowing power

efficient design implementation for various applications.

The device provides 25.8 dB of flat gain up to 1800 MHz, making

this ideal for Data Over Cable Service Interface Specification (DOCSIS)

4.0 downstream applications. The device is also well suited for

upstream applications to 700 MHz as the output stage. It is conveniently

packaged in an industry-standard, 5 mm × 5 mm, 32-lead,

lead frame chip-scale package (LFCSP) with an exposed pad on

the bottom of the package for improved thermal performance.
