Motorola’s STARLINE® series amplifier, model MB87*/*, leads the industry

The MB87 two-way
amplifier offers 870 MHz
bandwidth capability,
high gain, high output
level, ergonomics, and
superior distortion
performance.

MB87 870 MHz Amplifier

STARLINE Series

BENEFITS INCLUDE:

 870 MHz Enhanced Gallium Arsenide (E -GaAs) power

doubling technology

 High gain
 High output level
 Four diplex filter options
 Ease-of-use ergonomics
 15 dB return loss
 60/90 V powering
 Meets Telcordia GR-1098-Core voltage surge

requirements using surge waveforms as described in
IEEE C62.41

 FCC, CENELEC and CCC approved
 Bode equalization (thermal or auto controlled )
 15 ampere AC capability
 Optional return path ingress control and sta tus monitor
 Power factor corrected power supply
 Directional coupler –20 dB test points

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 opt ional 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.

ENHANCED GALLIUM ARS ENIDE

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.

HIGH GAIN

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

BACKWARD COMPATIBILITY

The MB87 electronics package can be made backward compatible with the 10 -Amp MB*/* housing by installing the MB ­15A Kit or the MB-15A Kit II. These kits contain 50 mil gold plated platform assemblies. This makes it possible for the
amplifier to carry 15 Amperes continuous through the input or out put ports.

FORWARD PATH

The operational gain of the MB87 is 34 dB or 40 dB depending on model , with 15 dB return loss. Output level control is
achieved through the use of an interstage Bode equalizer, which compensates for coaxial cable attenuation cha nges due
to temperature. Equalization may be controlled manually, with a thermal drive unit (model TDU) or with a single pilot
closed loop automatic drive unit (model ADU -* or QADU). Both the TDU and the ADU boards are common to the
STARLINE family of am plifiers (with the exception of the SLE) . ADUs utilize Surface Acoustic Wave (SAW) filters for
determining pilot frequency. This improves amplifier stability over temperature.

To further ensure system flexibility, installation ease and maintenance, the am plifier is engineered for compatibility with
standard accessories, such as attenuators, equalizers, ADUs or TDUs, return amplifiers, automotive fuses and FTEC ­BTA crowbar circuits.

For an optional third output, the MB87 utilizes splitters (model SP) and di rectional couplers (model DC/*). The SP, DC/8,
DC/10, and DC/12 offer superior performance to 1 GHz.

The MB87 uses modular diplex filters, which can be changed for a different frequency split as required. The amplifier is
available with S-split filters for a 5-40 MHz return and a 52 -870 MHz forward band. K-splits (5-42 MHz/54-870 MHz), J­splits (5-55 MHz/70-870 MHz), and A-splits (5-65 MHz/85-870 MHz) are also available. These same filters can be used
for all US-style Motorola RF distribution amplifiers (models BLE, MB/MBE, BT).

RETURN PATH

High gain return amplifier kits can be ordered which provide 20 dB minimum station gain. Return path equalizers from 0
to 12 dB can be customer selected. Optional features include thermal compensation and ingress con trol switching.
Thermal compensation comes in the form of a plug -in JXP-TH*C, which stabilizes gain and match over temperature
extremes.

Also available is Ingress Control Switching (ICS) in 3 states. This pin diode attenuator circuit can lower levels by 6 dB or
by 38 dB with a controlled slew rate for minimum bit errors. The dual output MB*/* requires two ingress control switches
when ordering this option (one ICS required for each output). The LIFELINE® MiniBridger Amplifier transponder, model
LL-MB-HMS-*/*, is required to operate the Ingress Control Switch from a remote location.

Model Availability

To reduce customer costs and to accommodate customer specific needs, the STARLINE MB 87 can be ordered in a
variety of different models. Please refer to the MB87 ordering information below for options.
