Keysight K281C
Coaxial Waveguide Adapter
18 to 26.5 GHz
Technical Overview
Key Features
Bi-directional, power can be
transmitted in either direction.
– Excellent repeatability.
– Measurement versatility
The Keysight Technologies, Inc.
K281C coaxial waveguide adapter
provides a convenient way of coupling
between waveguide and coaxial
systems. Power can be transmitted
in eithe r direction and each adapter
covers the full frequency range of its
waveguide size. A step-like internal
structure transforms the waveguide
impedance to the 50 Ω impedance of
the coaxial line.
