Cable Superior Technology

LA Series Cable

Provides the best combination of low attenuation, phase stability, and mechanical performance. Offers excellent bend and crush resistance. Suitable for phase stability over temperature and flexure.

HP Series Cable

A long-standing choice for military and aerospace industries, also excelling in test and measurement applications. Offers high performance, flexibility, and a wide range of precision connectors for applications up to 50GHz. Features triple shield construction for robust connector attachments.

SW Series Cable

Provides low loss cable solutions with exceptional electrical performance and simplified connector attachments. Offers a good balance of performance and cost.

KW Series Cable

Offers ultra-low attenuation and high power ratings comparable to rigid, corrugated, air dielectric cables, but with significantly improved flexibility. Features a copper clad aluminum conductor and a soft polyurethane jacket, ideal for tight installations.

SM Series Cable

A flexible alternative to semi-rigid cable, utilizing the same connectors and tooling. Ideal for applications requiring compact or densely-spaced coaxial interconnects, such as military ECM, commercial antennas, and communication systems. Offers >100 dB shielding effectiveness.

Connectors Overview

Semflex offers a large selection of microwave connectors designed for excellent electrical transitions and low VSWR. Hundreds of other connector designs are available for special requirements including high power, swept bends, environmental sealing, low intermod characteristics, and special plating.

Cable Insertion Loss Calculation

Formula: IL = L x [( k1 x F ) + ( k2 x F ) ] / 1200 + Connector Loss

Where:

• IL = Insertion Loss (dB)
• L = Length (in)
• F = Frequency (GHz)

VSWR Guide (Example for HPI/LAI Series)

*Contact factory for detailed VSWR specifications.

Power Handling

Average power ratings are based on VSWR of 1.0:1, at sea level and an ambient temperature of 25 C. Derating factors for temperature and altitude are available.

*Average power ratings of connector interfaces are typical for most applications and based on 900MHz.
