Cisco Compact Single Output EGC Amplifier A93280

The Cisco Compact Single Output EGC Amplifier A93280 addresses the divergent needs
of today’s broadband networks. It is optimized for both trunk and distribution applications

and provides superior reliability combined with a user-friendly layout.

The amplifier incorporates electronic gain control (EGC) technology and automatic gain control

(AGC) technology, and has an extendable frequency range up to 1 GHz. Frequency range can be

set to 862 MHz or 1 GHz. The tilt and gain can be set with a handheld terminal or PC configuration

kit without using the traditional plug-ins.

The amplifier has one forward active output port with high linearity. Reverse path can be set from

20 dB to 28 dB with 0.5 dB step. The bandwidth for reverse path is 120 MHz. Both forward and

reverse gain has wide dynamic range and can be set in 0.5 dB step.

The amplifier power consumption can be reduced approximately 2 W if high output level isn

’t

needed. Furthermore, the interstage gain-block can be powered off if the forward gain of the

amplifier is set to 32 dB to reduce power consumption.

The amplifier supports ROSA



element management through the HMS and SMC transponder

interface. A handheld terminal and PC configuration kit can also be used for local configuration.
