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), J-
splits (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.
