Details
Broadband House Amplifier Terra BA-214 R82415 is intended for amplifying and distributing RF signals in CATV networks. It is a new item in a range of broadband Terra amplifiers for CATV networks. The amplifier is equipped with output stage using Gal-As semiconductor components, working in push-pull mode. Its modular structure allows for optimum adjustment for system requirements. Appropriate plug-ins allow for equalizing channel levels and setting optimal interstage attenuation.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit. High level of output signal and built-in compensation of the cable attenuation characteristics allow for building large RF distribution systems.
Distinguishing features:
- Gal-As push-pull output stage
- waterproof die-cast housing providing high screening efficiency
- high maximum output level: 115 dBμV (for 42 channels)
- compensation of the cable attenuation (slope)
- test output -30 dB
