ACA4789

1218 MHz 25 dB Gain CATV Power-Doubler Amplifier


Please note: this product is being discontinued and is not recommended for new designs.

The ACA4789 is a highly linear, high-output power hybrid RF amplifier designed for CATV head-ends and HFC distribution systems. The module consists of two parallel amplifiers that are optimized for exceptionally low distortion, high-output power, and high crash point. A GaN output stage is incorporated to minimize the operating (bias) current, making this an excellent choice for environmentally friendly “green” initiatives.
