Cable Assemblies
• Enhanced torque and crush resistance
• 1.20:1 VSWR typical
• Stainless steel connectors
• Slotted N, ATNC interfaces
TRUcore™ 300 Series cable assemblies offer a new level of RF and microwave
performance combined with superior mechanical and environmental durability.
TRUcore™ assemblies are optimized for 18 GHz broadband electrical performance,
but also provide designers with a mechanically durable construction that will not
degrade under real life torque, vibration, crush or kinking forces that may be
critical in your application. TRUcore™ provides a flexible coax solution without
the need for supplemental armor or jacketing to protect the controlled density
core of the cable.
• Environmentally sealed
• Ideal for ground-based, sea
and airborne platforms
TRUcore™ 300 Series cable assemblies utilize an innovative core design that
provides excellent phase stability over temperature and offers greater than two
times the crush and torsional resistance of typical military specifications even
while remaining under load conditions. Our unique TRUtie™ cable-connector
attachment technology has been designed to eliminate the cable junction as a
point of mechanical stress failure, exceeding typical military specifications.
In addition to the broad range of standard configurations in this series, TRU
can also provide specific engineered solutions for your challenging applications.
Our experienced Applications Engineering team is available to personally work
with your design team to answer all your technical questions.

Standard Connector Options
TRUcore™ 300 Series cable assemblies are available in three standard connector interface configurations: SMA, type N
and ATNC. Each are designed specifically for use with TRUcore™ cable to optimize 18 GHz electrical performance and
ensure high levels of mechanical and environmental durability. Each connector features passivated stainless steel bodies
for long life and are environmentally sealed when mated. Type N and ATNC connectors feature slotted spring finger
interfaces and tie wire holes for use in applications where vibration may be present. Our unique TRUtie™ clamp
method for cable-connector attachment provides best in class retention and exceeds all reference military specifications.
Custom connector configurations are also available to meet your application requirement.
