The Line Extender III (LEIII) family
of RF amplifiers provide optimum
performance and reliability for
broadband network applications.  All
LEIII amplifier modules offer fifteen
amp current carrying capacity, and
are pre-configured with diplexers
and reverse amplifier for optimum
reverse performance.

The LEIII PHD amplifier module can
be field configured with a variety of
options to meet specific
requirements.

For applications where output level
control is not required, the interstage
is typically configured with a stand
alone Interstage Equalizer (ISEQ).

For basic output level control in
aerial plant applications, a
combination Thermal Compensator/
ISEQ is available.  

For the most accurate degree of
output level control in both aerial
and underground plant, a
combination AGC/ ISEQ is the
desired option.

The LEIII PHD amplifier module
provides one (bridger level) output.

• 60 and 90 V AC powering capability

• 15 ampere current capacity (steady state) and 25 ampere surge survivability

• Integrated reverse amplifier, with optimized diplex filter group delay for 

forward and reverse paths

• Reverse input test point and input pad allowing optimum reverse path 

alignment

• Unitized design (amplifier and power supply in a single module) enables 

simplified and faster maintenance

• High efficiency, transformer-less power supply lowers system operating cost

• Directional Coupler RF testpoints provide optimum accuracy

• Surge Resistant™ Circuitry ensures hybrid protection without fuses or other 

nuisance failure causing device
