Microwave coaxial cables on show at Military Communications Conference

Molex : 05 November, 2012  (New Product)
Molex Incorporated showcased new coax cables from Temp-Flexat the Military Communications Conference (MILCOM 2012) with improvements to electrical performance, low loss and bandwidth.

Designed for high-bandwidth applications using proprietary processes, Temp-Flex microwave cables are designed for monitoring and control of radar, military vehicles, satellite, space, missile, RF ablation and test and measurement equipment, Temp-Flex coaxial cables are insulated with a fluoropolymer dielectric. A helically-wrapped silver-plated copper flat-wire shield and braid are applied to all cable sizes to achieve superior shielding effectiveness. The standard solid core (low loss) construction coaxial cable delivers 70% velocity of propagation (VOP), while the air-enhanced dual monofilament design (ultra-low loss) achieves 85 to 88% VOP and improved insertion loss at high frequencies.

“Our flexible microwave and RF coaxial cables are engineered to meet or exceed the stringent requirements for a range of rugged industrial and military applications,” states Jeet Sanyal, engineering manager, Temp-Flex.

Temp-Flex microwave coaxial cables are available with either a solid core fluoropolymer resin dielectric (low loss) or an air-enhanced design with a fluoropolymer resin layer applied over dual monofilaments (ultra-low loss) around the center conductor for increased signal speed. High purity fluoropolymer resin offers a low dissipation factor and ensures a lower rate of energy loss. Highly consistent manufacturing processes are used to maintain tight mechanical tolerances yielding extremely stable electrical performance.

Additional benefits of Temp-Flex low and ultra-low loss microwave coaxial cable include:

  • Phase stability
  • Tight impedance tolerance: 50 Ohms ± 1 Ohm
  • Shielding effectiveness: > 100 dB
  • Tight time delay tolerance
  • Outstanding Insertion Loss
  • FEP alternative to PTFE and ePTFE
  • Bandwidth potential up to 110 GHz
  • Stability under dynamic conditions
  • Minimal phase change versus flexure
  • Low Smoke Halogen Free Available

Temp-Flex manufactures specialty wire and cable, and invests in research and development targeting the medical, aerospace, military, computer, electronics, test and measurement and industrial markets. Processing equipment and tooling are fabricated in Temp-Flex’s machine and fabrication shops. Temp-Flex employs an extrusion process that uses fluoropolymer insulation with a concentration on thin walls for the medical industry and faster speeds in the electronics industry. Typically designed for extreme conditions and harsh environments, all Temp-Flex product lines are RoHS compliant.
