ACA2428

The ACA2428 is a highly linear, high output power integrated RF amplifier designed for CATV heads ends and distribution systems. The IC consists of two parallel amplifiers that are optimized for exceptionally low distortion, high output power, and high crash point in a thermally enhanced surface mount package. A GaN output stage is incorporated to minimize the operating (bias) current, thus making this an excellent choice for environmentally friendly “green” initiatives. The ACA2428 provides high gain over the 40 to 1000 MHz CATV downstream band, and is cascaded between two transmission line baluns and one impedance matching transformer. It is powered through the center tap of the impedance matching transformer with a single +24 V supply.
