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.
