MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
The RF Line
550 MHz CATV
Feedforward Amplifier
Designed for broadband applications requiring low–distortion amplification.
Specifically intended for CATV market requirements. Two hybrid amplifiers
along with couplers and delay lines are packaged together to provide extremely
low distortion products at conventional CATV amplifier output levels.
• Specifically Designed to Provide Improved Performance in 550 MHz CATV Applications
• Distortion Components Reduced more than 20 dB from Conventional CATV Hybrid
Amplifiers
• Specified for 77–Channel Performance
• Fully Shielded Metal Package
