Motorola’s STARLINE


series amplifier, model MB87*/*, leads the industry

in features and performance and is designed to meet the needs of today's
expanding broadband communication networks. This two -way capable
dual output amplifier offers high gain, high output levels, ergonomics,
superior distortion performance, four diplex filter options, 15 dB return loss,
and Bode equalization. The MB87*/* also allows optional advanced
features such as ingress control switching and status monitoring. A third
output is user-configurable via splitter or directional coupler plug -in. Single
output models are also available.


The MB87 uses Enhanced Gallium Arsenide (E-GaAs) hybrids. This second generation technology provides superior
distortion performance in CTB and CSO over the standard GaAs technology. Compared to silicon and competing GaAs
technology, E-GaAs distortion performance remains linea r at significantly higher output levels. This higher output level
allows the customer to maximize system performance and reduce system costs. We encourage our customers to
contact their Motorola Account Representative to determine the optimal levels for their systems.


The MB87 also offers high gain. This allows the operator to hold existing amplifier locations during system upgrades
thereby reducing system costs.

The MB87 two-way
amplifier offers 870 M Hz
bandwidth capability,
high gain, high output
level, ergonomics, and
superior distortion
