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 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.

Distribution Amplifiers (QDAXU)
The reliable QDAXU amplifier offers 870 MHz or 1 GHz bandwidth and high output slope capability in a sturdy extruded aluminum housing with ample heatsinking. Shipped fully functional, it comes standard with active pushpull 5-42 MHz return amplification. It is available in either GaAs power-doubled or cascaded GaAs PD configurations, for industry-leading performance. The QDAXU amplifier is shipped complete with three extra input equalizers, which together with the variable gain and tilt interstage controls, make the unit fully operational in almost every installation without any accessories.

Distribution Amplifiers (QDEU)
The newest model of our QDE family, the QDEU, is a smaller version of the high performance QDAXU distribution amplifier, but utilizes push-pull GaAs technology for lower power consumption. It comes standard as a fully-active, 2-way amplifier, with 5-42 MHz return, and forward bandwidths of 870 MHz or 1 GHz. Wide range tilt and gain controls are located interstage for good composite triple beat control. The versatile variable input attenuator replaces the input pad, so there is one less pad to stock. With the QDEU you get low-noise and low-distortion GaAs technology in a smaller package, at an affordable price.

Isolation Amplifiers (QCIA)
The QCIA 17 dB gain isolation amplifiers with an internal directional coupler, prevent cross-talk with multiple channel line-ups. The push-pull or power-doubled single amplifier version is similar to the QRBA amplifier. The amplifiers are housed in an MDU panel/wall mount housing. The circuit board has been tested to 1 GHz.

Distribution Amplifiers (QDAXS)
Built on the QDAX platform above, the QDAXS includes an additional interstage equalizer for applications needing highly sloped output levels. The QDAXS 870 MHz amplifiers are available in power-doubled and quadra-powered hybrid technology. This array of technology affords the system designer a level of RF flexibility not present in more typical CATV multi-dwelling amplifiers. Integral diplex filters provide for a 2-way, 5 to 40 MHz return path. Variable gain and slope control, plug-in hybrids and accessories, and an internal reverse sweep insertion port are other features of this line.

Distribution Amplifiers (QDAXF)
The QDAXF utilizes a user-selectable fixed pad and equalizer in the interstage, in place of variable controls, in order to provide both high output slope and excellent overall performance at 870 MHz. Output options are available in power-doubled or quadra-powered hybrid technology. Integral diplex filters provide for a 2-way, 5 to 40 MHz return path. The interstage EQ and pad set output levels. Other features include plug-in hybrids and accessories, and an internal reverse sweep insertion port.

Distribution Amplifiers (QDES)
The QDES is a smaller version of the high performance QDAX distribution amplifier using push-pull technology. The 550 MHz model offers a single power-doubled hybrid of 18 or 20 dB gain in both 1-way and 2-way versions. A 5 to 200 MHz, 43 dB gain push-pull model is 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.
