The HA-214R65 house amplifier is a professional device used in SMATV and cable systems with return channel. The chip of the HA-214R65 amplifier at the penultimate gain stage is made of SiGe silicon-germanium nanostructures (silicon-germanium chip). Such a solution allows significant reduction of non-linear distortion, especially when it comes to second-order distortion. The final stage in the reciprocal circuit is made of gallium arsenide (GaAs).
The use of dual-circuit technology, consisting of an attenuator and a waveform correction filter, makes it possible to ensure the best possible signal performance (high signal-to-noise ratio).
The enclosure provides high shielding effectiveness preventing the penetration of interfering signals into the device. High output signal level and built-in pre-correction of attenuation characteristics of coaxial cables allows for making large systems.
Key features:
  • push-pull output stage made of gallium arsenide GaAs
  • waveform correction at the input of the transmission channel
  • waveform correction between stages one and two of the transmission channel
  • attenuator at the input of the transmission channel
  • possibility to switch on or off the amplifier at the return channel
  • attenuator at the input of the return channel
  • waveform correction at the output of the return channel
  • attenuator at the output of the return channel
  • test connector -20dB
