Technology Roadmap

• Far beyond open or short to full
  electromagnetic transmission lineswith
  characteristics like
• Return loss (VSWR)
• Attenuation (insertion loss)
• Propagation velocity
• sometimes expressed as of speed of light
• Dielectric constant (Dk)
• Conductivity
• Frequency
• Flexible cable
• Unique wrapped tape technology to enable both
  flexure and low Dk
• diameter of OD of cable jacket fitness for use
  issue
• Dimensionals
• Outside diameter of center contact, inside
  diameter of braid, concentricity

7
Core Competency Coaxial Cable Design
Computer Aided Design which models for
attenuation optimization and other performance
criteria based on selection of braid, foil,
dielectric spacing, materials considering cost
and other performance tradeoffs (flexibility,
durability, size, weight, environmental factors).
8
Core Competency Cable Manufacturing

• State of the Art Cable Production Equipment
  provides process controls for product uniformity
• Concentricity
• Dielectric spacing
• Repeatability within lot and lot to lot.

9
Product result bulk Cable

• High Performance Coaxial Cable
• low loss - 60mils to 800 mils diameter
• of PTFE dielectric
• superior propagation velocity, ultra low
• dielectric constant.
• high frequency
• up to 129 GHz (theoretical cutoff frequency)
• high power
• up to 13.5 KW _at_ 1GHz
• High end M17 (RG type) cable plus twinax and
  triax RF cables.

10
Core Competency Connector Design
Semflex has 20 years of custom RF and microwave
connector design experience. With this, and
now CAD/CAM design tools, our capability to
provide unique connectors matched to the cable
for impedance, phase, and attenuation is
extraordinary.

Semflex - not just another cable assembly
supplier

• Full ISO9001 certification for several years now
• Focused on high frequency transmission lines
• Recognized partner at Lockheed Martin
• STAR supplier, down-selected, analyzed,
  scrutinized, measured, and rated against all the
  others - and then selected as one of a handful of
  companies that meet the rigorous criteria of a
  major aerospace/defense contractor for multiyear
  positioning to achieve excellence in their
  subcontractor base, building toward higher
  performance with shorter product leadtime and
  lower cost.
• And test capability that is truly unique

19
Test Capabilities

• Network Analyzers return loss and attenuation
  to 40 GHz in house, higher frequencies are
  subcontracted as an outsource.
• High power handling test for special requirements
  like lasers and sputtering equipment.
• Navy and US Air Force mechanical performance
  criteria testing (flight hardware).
• Other special testing for environmental,
  electrical, and mechanical criteria.

20
The Semflex Sweet Spot

• Clearly, Semflex is focused to deliver value on
  shielded transmission lines, typically one with
• Microwave bulk cable
• Custom coaxial cable assemblies, interconnect
  cables, test cables
• Where there is Semflex cable content
  (manufactured)
• Generally 50 ohm
• Generally tends to be microwave (gt1 GHz)
• Generally involves insertion loss, VSWR, phase
  length, power handling, and/or time delay
  (propagation velocity).
• Semi-rigid cable assemblies
• Adapters, phase trimmers, and other custom
  components manufactured by Semflex
