Professional CATV Amplification for Broadband Networks

The KEJIAN 834 series hybrid integrated circuit is a critical component for modern CATV (Community Antenna Television) and broadband distribution networks. Engineered to operate over the 40MHz to 860MHz frequency spectrum, this module provides stable, high-gain signal amplification essential for delivering quality television and data services to subscribers .

Why Choose KEJIAN 834 CATV IC?

High Gain & Wide Bandwidth: With a gain of 34dB across the entire 40-860MHz range, the KEJIAN 834 amplifies weak upstream and downstream signals effectively. This ensures consistent signal integrity across long cable runs and multiple subscriber taps .

Excellent Signal Purity: The module is designed with excellent linearity and extremely low noise characteristics . Low noise figure and high distortion performance mean that the amplified signal remains clear and free from artifacts, which is crucial for digital TV and DOCSIS cable modem data.

Robust Hybrid Construction: Packaged in a hermetically sealed SOT115J hybrid module, the KEJIAN 834 is built to withstand the rigors of outdoor CATV plant operation (e.g., in amplifier housing and optical nodes). It offers excellent return loss properties, minimizing signal reflections.

Specific to CATV Infrastructure: The KEJIAN 834 is specifically designed for use in:

CATV Line Extenders: Boosting signals in the distribution leg.

Optical Nodes: Converting optical signals back to RF and providing the initial amplification stage.

Trunk Amplifiers: Maintaining signal levels along the main distribution backbone.

Compatibility & Selection:

KF834N-24: Operates at 24V DC, standard for most line extender applications .

KB834H-3.5: Operates at 3.5V DC with optical input capabilities .
