Description
HF-290
HF-290 is an Ultra low loss, flexible microwave coaxial cable which provides excellent performance over the DC-18 GHz frequency range. HeliFoil cable comes in four different sizes, with options of stranded centre conductors for better flexibility.
HeliFoil-290 provides lowest attenuation, excellent phase stability, broad operating temperature range and high power handling, making this cable a good choice for interconnect and testing applications in both field and laboratory conditions.
HF-290 Features & Benefits:
- Lowest Insertion Loss Available, DC-18GHz
- Ultra Stable Loss, Phase and VSWR with Flexing
- Excellent Phase Tracking Performance over Temperature
- Extremely Flexible, Low Minimum Bend Radius
- Superior Shielding Effectiveness (>100 dB)
HeliFoil Cable Construction
- Centre Conductor: Silver Plated Copper
- Dielectric: Expanded Taped PTFE
- Shield: Helical Silver Plated Copper Tape
- Outer Braid: Silver Plated Copper Braid
