MB*/* Installation and Operation Manual
Section 1
Introduction
The Motorola
®
STARLINE
®
series of MiniBridger amplifiers, model MB*/*, accept a single input
and provide high operational gain to a single or dual output. The high gain makes the MB*/*
series ideally suited for a hybrid fiber-coax system as well as conventional tree-and-branch
designs. The MB*/* amplifier series complies with IEEE C62.41-1991 and Bell Core GR-1098
specifications for overvoltage testing as recommended by Cable Labs. The MB*/* platform is
also FCC and CE approved.
Features of the MB*/* include:
750 MHz or 870 MHz power doubling technology
(in enhanced gallium arsenide (E-GaAs) or silicon)
Several different modular diplex filter splits
“Ease of use” ergonomics
60/90 Vac line power option
Power factor corrected power supply
Thermal and auto-controlled Bode equalization
−20 dB directional coupler test points
Optional return path ingress control and LIFELINE
®
status monitor
Two-way capability
15-amp power passing
Features of the optional MB*/* bypass housing include:
Amplifier bypass for maintenance and upgrades
Accommodation of the optional bypass amplifier
Use of a quick-connect interface probe for RF/AC bypassing
A reversible amplifier module
90-degree port entries
15-amp, 1 GHz electrical performance
