Motorola’s 1 GHz STARLINE
®
Mini-Bridger
®
series amplifier, model
MB100*, 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, multiple diplex filter
options, 16 dB return loss, and Bode equalization. The MB100 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.
ENHANCED GALLIUM ARSENIDE
The MB100 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 linear 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 MB100 also offers high gain, which allows the operator to hold existing amplifier locations during system upgrades
thereby reducing system costs such as maintenance, installation and powering.
The MB100 two-way
amplifier offers 1 GHz
bandwidth capability,
high gain, high output
level, ergonomics, and
superior distortion
performance with the
option to bench upgrade
to N-split (5-85/104-1003
MHz) in the future.

BACKWARD COMPATIBILITY
The MB100 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 output ports. There is also a “low current” (10A) model
available that can be ordered as an electronics module (no housing included), which is backward compatible with the 10-
Amp MB housing, without the use of a kit.
FORWARD PATH
The operational gain of the MB100 is 42 dB, with 16 dB return loss. Output level control is achieved through the use of
an interstage Bode equalizer, which compensates for coaxial cable attenuation changes due to temperature.
Equalization may be controlled manually, with a thermal drive unit (TDU), or with a single pilot closed loop automatic
drive unit, model ADU-* (analog pilot) or QADU-* (QAM pilot). Both the ADU and QADU boards are common to the
STARLINE family of amplifiers (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 amplifier is engineered for compatibility with
standard accessories, such as attenuators, equalizers, ADUs or QADUs, return amplifiers, automotive fuses and FTEC
crowbar circuits.
For an optional third output, the MB100 utilizes splitters (model SP100) and directional couplers (model DC100/*). The
SP100, DC100/8, DC100/10, and DC100/12 offer superior performance to 1 GHz.
The MB100 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 52-1003 MHz forward band. K-splits (5-42 MHz/54-1003 MHz),
J-splits (5-55 MHz/70-1003 MHz), and A-splits (5-65 MHz/85-1003 MHz) are also available. The N-split (5-85 MHz/104-
1003 MHz) option is currently in development. 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 control 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 LIFELINE
®
Mini-Bridger amplifier transponder (available
directly from AM Networks) 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 MB100 can be ordered in a
variety of different models. Please refer to the MB100 ordering information below for options.
