Part Number Description
PRODUCT DESCRIPTION
1. Product Description
The QMP1000 MAXNET II modules are Forward RF Ampliers, which offer various gains that are determined at the
time of ordering. The lower gain ampliers (17 dB and 21 dB gain) operate in a single stage manner as shown in the
functional diagram – Figure #1, Page 6. The higher gain ampliers (28 dB, 31 dB and 34 dB gain) operate in a dual stage
process as shown in the functional diagram – Figure #2, Page 6. The QMP1000 ampliers are dual-width modules, taking
up two slots in the Active MAXNET II Chassis and they are powered through a hot-swapping backplane. An appropriate
MAXNET II Power Supply in the Active MAXNET II Chassis powers these modules. The QMP1000 modules feature the
standard MAXNET II functionality including high-density packaging through the use of MCX coaxial cable connectors (F
connectors are available as option) 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.
