Overview

911 series High Power Attenuators

The High Power Attenuator with a movable short, is used to introduce a fixed standing wave ratio in a waveguide transmission line. By means of the movable short the phase of the standing wave can be varied. This set up is very suitable for determining the characteristics of high power magnetrons and klystrons, and for studies of break down in high power systems and components.

913 series High Power Terminations

The High Power Terminations are capable of dissipating large amounts of power without producing undesirable reflections in the waveguide system.

Features

911 series High Power Attenuators

When the Attenuator is terminated with a short, the VSWR introduced in the transmission line for an attenuation of 7.0 dB is 1.5 and for 4.8 dB 2.0.

913 series High Power Terminations

Listed standard terminations are made in aluminum and are available with VSWR of 1.05 in narrower bandwidth than 20%. Special versions with other flanges, higher power capability and other dimensions are available on request.

Applications

911 series High Power Attenuators

The VSWR 1.5 and 2.0 are typical for testing magnetrons and klystrons. The High Power Attenuator can also be used in any other application where one desires to decrease the power to a more suitable level for the test gear in use.

913 series High Power Terminations

The High Power Terminations are intended to be used as dummy loads for high power microwave transmitters. Their low VSWR, small dimensions and moderate price level also make them suitable for use in laboratories as Low Power Terminations.
