Specification of Coupler

The HA-GaAs-33 amplifier is intended to be used as a group amplifier in limited cascades (2 to 3 amplifiers), and as a final amplifier for high-density areas.

The use of GaAs technology allows operation at high gain (33 dB) and a high output level. The HA-GaAs-33 is especially designed for cost-effective upgrading of all kinds of networks up to 870 MHz.

Interstage pre-equalization functions allow the amplifier to operate over large gain and level windows.

Different plug-in Return-Path modules can equip for future services such as interactive TV and data transmission.

Key benefits:

High output level but low power consumption by use of GaAs technology

High performance local or remote power supply with power factor compensation (option)

Return path with high gain transmission of upstream signals (telephony, Internet, VOD)

Greater reliability network

Extremely low Price conditions
