The LE1200 line amplifier thanks to it's modular style and to the 3 different gain values can be adapted to each
CATV network. The automatic controlled return path ingress switch, the dividable high level output, the module
defined breakpoint frequency and the optional AGC unit as well as the exchangeable tray make the device the
best choice for HFC solutions.
Benefits :
• Downstream frequency range up to 1218 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• GaN output stage
• Automatic gain and slope control
• Automatic ingress management by the RSW module.
