Cisco Legacy System Amplifiers

High-Performance RF Amplifiers

As part of Scientific Atlanta's commitment to supply our customers with the latest technology, and as a result of the announced obsolescence of some critical components, we are discontinuing the SA III and LE III System Amplifiers and Line Extenders effective March 3, 2008 and replacing them with Cisco GainMaker System Amps and Line Extenders.

The System Amplifier III (SAIII) family of RF amplifiers includes a variety of gain, output, and frequency configurations to suit various network architectures. These amplifiers incorporate features to increase current-passing capability by as much as 50 percent while improving tolerance to current surges - resulting in lower repair and replacement costs.

Features include:

  • 60 and 90 VAC power
  • 15 ampere (A) current capacity (steady state) and 25A surge survivability
  • Integrated reverse amplifier for two-way applications
  • High-efficiency, transformerless power supply for lower system operating
  • Surge-resistant circuitry for hybrid protection without fuses or other failure-prone devices
