DATA SHEET ACA2429: 1218 MHz High-Output GaN CATV Power-Doubler Amplifier Applications Advanced high-power, high-frequency HFC transmission systems Output power doubler for deep fiber node in CATV distribution CATV digital edge QAM output driver Features 50 to 1218 MHz frequency range Output power: +59 dBmV Description Gain: 25 dB at 1218 MHz The ACA2429 is a highly linear, high-output power integrated RF 1 dB tilt over bandwidth amplifier designed for CATV head-ends and HFC distribution Single +24 V supply systems. The IC consists of two parallel amplifiers that are optimized for exceptionally low distortion, high-output power, and Operating current: 430 mA high crash-point in a thermally enhanced surface-mount package. GaN amplifier technology A GaN output stage is incorporated to minimize the operating Halogen-free/RoHS compliant (bias) current, thus making this an excellent choice for environmentally friendlygree initiatives. The ACA2429 provides high gain over the 50 to 1218 MHz CATV downstream band, and is cascaded between two transmission line baluns.
