High power building amplifier Terra BA-203U has been designed for amplifying and distributing TV signals in CATV networks with return channel. Its output stage uses GaAs push-pull technology. Modular construction allows customization for specific network requirements. The changeable plug-in return path module shaping the frequency characteristics of the return channel can use passive or active components. Appropriate plugins can also shape the frequency response of the forward path and determine the interstage attenuation.

Main features:

• push-pull output stage in GaAs technology,
• waterproof housing with high screening efficiency,
• equalizer at the input of the forward path,
• interstage equalizer between the first and second stage of the forward path,
• attenuator at the input of the forward path,
• attenuator between the first and second stage of the forward path,
• choice of active or passive return path by using the appropriate plugin,
• equalizer at the output of the return channel,
• attenuator at the output of the return channel,
• -20 dB input test point (bidirectional),
• -20 dB output test point (directional).
