Opis
House/building amplifier HA-205R65 is equipped with output stage using Gal-As semiconductor components, working in push-pull mode. The amplifier has been designed for cable and MATV systems with return path/channel and enables signal level equalization in forward and return path.
Another advantage of the HA-205R65 amplifier is the driver stage based on SiGe (silicon-germanium) chip. This solution significantly reduces nonlinear distortion, especially that of the second order.
The amplifier has built-in attenuator, test connectors (-20 dB), active return path, and allows for compensation of the cable attenuation dependent on frequency. All connectors are of the F-type.
The compensation circuits have two stages in order to guarantee maximum signal-to-noise ratio.
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.
