Agilent/Keysight S281A

The Agilent/Keysight S281A is a coaxial waveguide adapter designed to convert waveguide transmission lines into 50-ohm coaxial lines. This device operates within the S-band frequency range, specifically from 2.6 to 3.95 GHz. It is constructed with a Type-N female coaxial connector. The S281A is engineered to handle power transmission in either direction across its specified waveguide band. The maximum SWR (Standing Wave Ratio) is rated at 1.25, ensuring efficient signal integrity. The physical dimensions of the adapter include a length of 140 mm (5.5 inches) and a shipping weight of approximately 0.54 kg (1.19 lb). This product is considered obsolete, and no direct replacement has been identified by the manufacturer.
