Anritsu TOSLK50A-20 – Coaxial calibration kit Type K(m) 50ohms

The Anritsu TOSLK50A-20 is a Type K(m) coaxial calibration kit engineered for precise RF and microwave measurements across DC to 20 GHz. This 50-ohm system delivers the calibration standards

Open, Short, Load, and optional Thru - required for SOLT (Short-Open-Load-Thru) calibration procedures on vector network analyzers and precision test instruments. The kit maintains exceptional return loss performance: ≥42 dB from DC to 10 GHz and ≥36 dB from 10 to 20 GHz on the load standard, ensuring accurate network characterization in both laboratory and field environments.
