MDU Solutions Apartment Amplifiers

As the broadband network has evolved, the need for higher performance, full-featured MDU amplifiers has become a necessity. ATX Networks is proud to offer the QDAXU and the QDEU, which are built on the solid foundation of our legacy QDAX and QDE platforms offering 1 GHz performance, reliability, and the added features needed in 2-way digital networks. Whether for use in a multi-dwelling for house drops, in large metropolitan high-rise apartments, or for campus/institutional applications, the QDAXU and QDEU amplifiers provide both excellent performance and high functionality in an economical package. In addition, the QCIA isolation amplifier prevents signal feedback that can cause co-channel interference, allowing clear local access channels, customized advertising insertion channels, RF modems and Telco signals to be sent to targeted franchise areas. Legacy distribution apartment amplifiers include the following: QDAX, QDAX-2W, QDAXS, QDAXF, QDE, QDE-Jr and QDES.

  • Features
  • Specs & Order Info
  • Solutions

QDAXU

  • 870 MHz or 1 GHz bandwidths and high level/high slope output capability
  • 2-way, 5-42 MHz return amplification
  • Available in GaAs power-doubled or cascaded GaAs PD configurations
  • Shipped with 3 extra input equalizers
  • Variable gain and tilt inter-stage controls
  • Fully operational in almost every installation without any accessories

QDEU

  • 870 MHz or 1 GHz bandwidths and high level/high slope output capability
  • 2-way, 5-42 MHz return amplification
  • A smaller version of the QDAXU, but utilizes push-pull GaAs technology for lower power consumption, as well as low noise and low distortion at an affordable price
  • Variable gain and tilt inter-stage controls
  • Variable input attenuator replaces the input pad, so there is one less pad to stock

QCIA

  • 870 MHz or 1 GHz bandwidths in push-pull or power-doubled configurations
  • High isolation output insertion point for local insertion
  • Prevents signal feedback that can cause co-channel interference, allowing signals to be sent to targeted franchise areas
  • 17 dB gain isolation amplifier with an internal directional coupler to prevent cross-talk with multiple channel lineups

QDAX

  • 870 MHz bandwidth in push-pull, power-doubled and quadra-power output technologies
  • 2-way, 5-40 MHz return amplification
  • Variable pin diode gain and tilt controls
  • Plug-in hybrids and accessories
  • Plug-in pads and EQs available at input to provide more uniform carrier-to-noise performance at all frequencies

QDAXS

  • 870 MHz bandwidth in Silicon power-doubled, Silicon quadra-powered, GaAs power-doubled and cascaded GaAs power-doubled technologies
  • Built on the QDAX platform above, the QDAXS includes an additional inter-stage equalizer for applications needing highly sloped output levels
  • Integral diplex filters provide for 2-way, 5-40 MHz return amplification
  • Internal reverse sweep insertion port
  • Variable gain and tilt controls
  • Plug-in hybrids and accessories
  • Plug-in pads and EQs available at input to provide more uniform carrier-to-noise performance at all frequencies

QDAXF

  • 870 MHz bandwidth in power-doubled and quadra-powered technologies
  • Utilizes a user-selectable fixed pad and EQ in the inter-stage, in place of variable controls, in order to provide high output slope and excellent overall performance
  • Integral diplex filters provide for 2-way, 5-40 MHz return amplification
  • Inter-stage EQ and pad set output levels and provide slope range far beyond normal slope and gain circuits
  • Plug-in hybrids and accessories
  • Internal reverse sweep insertion port

QDE

  • Forward bandwidths up to 550 MHz
  • A smaller version of the high performance QDAX distribution amplifier using push-pull technology
  • Available in 1- or 2-way models, 5-32 MHz return amplification
  • Can be configured as 1- or 2-stage hybrid amplifier
  • Traditional tilt and gain controls are located inter-stage for good composite triple beat control
  • Variable gain and tilt controls
  • RF input pad and EQ ensure easy carrier-to-noise management
  • Plug-in hybrids, return attenuators, pads and accessories

QDE-Jr

  • Forward bandwidths up to 860 MHz
  • Fixed-tune, push-pull technology in a compact size
  • Single-hybrid amplifier configured to serve house drop or low-power distribution amplifier applications
  • Available in 1- or 2-way models with 5-30 or 5-40 MHz return path amplification
  • Variable gains and sub return models for headends
  • Fixed-tuned with full range of pads and EQs
    Gains: 17, 21, 25 or 32 dB

QDES

  • Forward bandwidths up to 550 MHz
  • A smaller version of the high performance QDAX distribution amplifier using push-pull technology
  • 550 MHz model offers a single power-doubled hybrid of 18 or 20 dB gain in both 1- and 2-way versions
  • 5-200 MHz, 43 dB gain push-pull model also available for return path applications
  • An input pad and EQ are used to set the signal levels on all QDES amplifiers eliminating tilt and gain controls

A new generation at work.

The I-HUB platform is ideal for minimizing fiber for Node+0, hub eliminations, node segmentations and RFoG, or reclaiming existing fibers for additional broadband subscriber narrowcast services and revenue generating business services. Learn more about this product.>
