Overview

PT Series precision test cables cover RF and mmWave measurements up to 110 GHz by configuration. A 10-layer armored construction supports repeatable interconnects in R&D, calibration and field setups.

Choose the cable type and connector pair for the required band and handling conditions. Loss, VSWR, amplitude stability, phase stability and bend radius vary by model; PT110 stability values require confirmation during configuration.

Additional product details

The PT Series test cable, covering DC to 110 GHz by configuration, is a high-performance interconnect solution specifically engineered for precision measurement.

Designed for durability, the cable offers superior crush and torque resistance, maintaining performance integrity through rigorous bending cycles.

Key Capabilities & Applications

Select the frequency configuration

Cable types include PT18, PT18S, PT26, PT26S, PT26L, PT40, PT50, PT67 and PT110. The assembled frequency range depends on cable and connector choices.

Compare performance by model

PT40 and PT50 have maximum VSWR of 1.3; PT67 is 1.4 and PT110 is 1.45. Cable loss and phase/amplitude stability must be read against the same model column.

Match connectors and handling

Connector families include SMA, N, 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm and 1.0 mm. Minimum bend radius and mechanical endurance are model-specific.

Common applications

  • mmWave component verification up to 110 GHz
  • VNA calibration
  • R&D laboratory testing
  • Field testing
