MB100 1 GHz Amplifier

STARLINE® Series

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 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.

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.

BACKWARD COMPATIBILITY

The MB100 electronics package can be made backward compatible with the 10-Amp MB*/* housing by installing the MB15A 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 10Amp 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/1041003 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.
