Description

The ACA1212 is a highly linear, high output power integrated RF amplifier designed for CATV head ends and HFC distribution systems. The IC consists of two parallel amplifiers cascaded between transmission line baluns that are optimized for exceptionally low distortion, high output power, and high crash point in a thermally enhanced surface-mount package. The ACA1212 covers the full 50 to 1218 MHz CATV downstream band demanded by DOCSIS 3.1 systems.
