GENERAL DESCRIPTION

The ADCA5190 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.

The device provides 19.1 dB of flat gain up to 1800 MHz, making

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

SIS

for upstream applications to 700 MHz as the output stage. The

device is conveniently packaged in an industry-standard, 32-lead,

5 mm × 5 mm lead frame chip-scale package (LFCSP) with an

exposed pad on the bottom of the package for improved thermal

performance.
