Precision Fixed Terminations

3.5mm Connectors (8031 Series), DC to 34 GHz
2.92mm (K) Connectors (8775 Series), DC to 40 GHz

Description

The 8031 and 8775 series fixed terminations (utilizing 3.5mm and 2.92mm connectors respectively) are precision, broadband, low VSWR terminations suited to a wide variety of general purpose and precision laboratory applications. Depending upon the frequency range and required calibration effectiveness of a vector or scalar network analyzer (VNA or SNA, respectively), specific models can be used for full or lowband one-port Z0 calibration and full two-port isolation calibration. The connectors on both model series are fully mating compatible with SMA and can be used in test applications requiring a low VSWR termination with that connector. They are also mating compatible with each other and can be interchanged in applications where the frequency range is compatible.
