Variable Precision Waveguide Attenuators
These precision
variable attenuators with a range of 0 to 40 dB at a maximum VSWR of 1.15 are
designed to provide an extremely accurate, completely shielded attenuating
device, having excellent stability regardless of age or wide variations in
humidity and temperature.* They are widely used for padding purposes, for
precisely controlling R.F. flow as a power setting device in waveguide networks.
These instruments incorporate precision metallized attenuating elements
of the parallel vane type, which are bilaterally matched to provide low VSWR
values over the frequency range of the unit. Attenuation is controlled by
means of a smooth operating mechanism which is free of backlash or play. A
counter-clockwise rotation of the control knob increases attenuation.
Alternate flanges and materials are available. See flange section.
Finish is instrument gray enamel.
