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
