GENERAL DESCRIPTION

The ADCA5191 is a medium power gain block amplifier that pro-

vides excellent linearity across a flexible bias range allowing power

efficient design implementation for various applications.

APPLICATIONS

► 45 MHz to 1800 MHz CATV infrastructure amplifier systems

► 5 MHz to 700 MHz upstream

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

this ideal for Data Over Cable Service Interface Specification (DOC-

SIS) 4.0 downstream applications. The device is also well suited for

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

iently 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.

► Remote physical layer (PHY)

► DOCSIS^®3.1 and DOCSIS 4.0 compliant
