Overview

GL Series phase-stable cables cover DC to 26.5 GHz by configuration. Flat silver-plated tape shielding supports phase and amplitude stability, with stainless-steel and nylon armor choices for different mechanical requirements.

Select the cable type, connector pair and assembly length together. GL, Low Loss and Ultra Flex constructions have separate electrical and mechanical specifications; connector-dependent VSWR limits also differ.

Additional product details

For outdoor base-station and dynamic-flexure measurement workflows, the GL series offers multiple armor options including stainless steel and nylon to support crush and torque resistance while maintaining measurement repeatability.

Key Capabilities & Applications

Maintain measurement stability

GL phase stability is 1° from DC to 10 GHz and 2° from 10 to 18 GHz. Amplitude stability is 0.05 dB from DC to 26 GHz, with shielding effectiveness greater than 100 dB.

Match construction to handling

The GL cable has a 20 mm minimum bend radius and a −55 to +125 °C temperature range. Low Loss and Ultra Flex constructions use different bend-radius and mechanical specifications.

Configure the complete assembly

Cable codes cover 3, 6, 18 and 26.5 GHz. Connector choices include SMA, N, 3.5 mm and BNC families; final coverage and VSWR depend on the selected assembly.

Common applications

  • Phase-stable RF measurement interconnects
  • Outdoor base-station test setups
  • Harsh-environment RF measurement
  • Dynamic-flexure measurement repeatability
