ATX HFC Amplifiers
GigaXtend HFC amplifier portfolio is a family of 1.2 GHz Line Extenders (LE) and System Amplifiers (SA) that offer MSOs both an upgrade path for their current installed base of amplifiers and the opportunity to invigorate their outside plants with technology built to accommodate future spectrum increases and bandwidth demands.
The GigaXtend family of amplifiers is built on Cisco’s trusted and well-regarded technology foundation with a reputation for performance and reliability. Since being selected by Cisco® to carry on the legacy of its industry revered GainMaker® amplifiers, Digicomm's Partner ATX has worked to make it as easy and seamless as possible for current GainMaker customers to protect and grow their existing investments.

GigaXtend GMC 1.2 GHz Line Extender
The ATX 1.2 GHz GigaXtend™ GMC Line Extender broadband amplifier is designed to assist cable operators in evolving their HFC networks to meet subscriber demand, while fully leveraging previous investments. Gallium Nitride (GaN) technology supports RF output levels up to 57 dBmV. The ATX GaN amplifier provides one high-level forward RF output.
ATX 1.2 GHz GigaXtend GMC Line Extender modules have increased gain to allow drop-in for 750 MHz, 870 MHz and 1002 MHz spacing. Backward compatibility often allows upgrades to higher bandwidth with no respacing or resplicing. The DC power supply is modular and located in an updated housing lid for easy access. All ATX 1.2 GHz Line Extender modules are factory configured with reverse amplifier, diplex filters, thermal compensation circuit, forward interstage pads and equalizer to promote optimal performance. Optional single-pilot Automatic Gain Control (AGC) configurations are also available.

Gainmaker® 1.2 GHz Forward Cable Equalizer
Forward cable equalizers are used during station balancing to compensate the tilt produced by coaxial cable in order to achieve the desired flatness.
Gainmaker® 1.2 GHz Inverse Equalizer
Simulates cable equivalent tilts (creates tilt opposite that of equalizers). Use in place of forward input EQ as needed to maintain proper output tilt in short spaced locations.
Gainmaker® 1.2 GHz Forward Linear Equalizer
Forward Linear Equalizers produce linear tilt. A Linear Equalizer will need to be used in the plug-in input or interstage equalizer location if a node output tilt does not have the desired station output tilt. The EQ “value” is the amount of tilt from lowest to highest frequency (52-1218 MHz).
Usage: GainMaker System Amplifier, Line Extender, and Node
204 Mhz Reverse Equalizers
Digicomm offers a complete line of 204 MHZ Reverse Equalizers from 1 dB through 20 dB in 1 dB increments. The reverse equalizers are designed to produce a tilted frequency response opposite of what is produced by the coaxial cable.
1.2 GHz Attenuator Pads
Digicomm offers a complete line of 1.2 GHz Attenuator Pads from 0 dB to 20.5 dB in 0.5 dB increments and 21 dB to 25 dB in 1 dB increments, as well as a 75 ohm terminator. Pads are used to attenuate excess signal and to produce flat loss across forward and reverse frequency spectrums. Pads are used during station balancing to adjust amplifier signal level as needed. The dB loss produced is equal to the value printed on the pad.
Tolerance:
+/- 0.3 dB (0 dB - 14.5 dB)
+/- 0.5 dB (15 dB - 25 dB)
1.2 GHz Signal Directors
Digicomm offers a complete line of 1.2 GHz Signal Directors. Signal Directors are used in High Gain Dual and Low Gain Dual system amplifiers only. An amplifier requires one signal director to route and/or split the forward RF signal to the Auxiliary output port(s). The signal director is available as a jumper, splitter, and directional coupler.
