PRODUCT DESCRIPTION

1. Product Description

The QMP200 MAXNET II modules are Return RF/IF Ampliers, which offer two gain versions (20 dB and 28 dB) that are
determined at the time of ordering. The QMP200 amplier is a single stage amplier as shown in the functional diagram. The
QMP200 ampliers are dual-width, taking up two slots in the Active MAXNET II Chassis and they are powered through a

hot-swapping backplane in the Active MAXNET II Chassis. An appropriate MAXNET II Power Supply in the Active MAXNET II
Chassis powers these modules. The QMP200 modules feature the standard MAXNET II functionality including high-density

packaging through the use of MCX coaxial cable connectors in conjunction with Mini RG-59 Type coaxial cable. Also featured

are: front access alarm LED indicator, -20 dB test points and the capability of module status monitoring through SNMP based
Managers. The MAXNET II SNMP interface is HMS compliant.
