Rotary Vane Attenuators
These extremely stable rotary vane type
variable attenuators provide high stability, well-shielded, efficient high level
attenuation for a wide range of applications, such as: isolating
oscillators and other microwave devices; adjusting power levels in microwave
networks; and reducing reflection in waveguide circuits.
An extremely flat attenuation characteristic is provided over the full waveguide operating frequency range, at any value of attenuation by virtue of the linear characteristic obtained with a rotary vane type device.
The units consist of a circular waveguide section mounted in a case, to which optimized waveguide transitions are attached. A thumbwheel located on the circumference of the rotary section provides a means of adjusting attenuation values which are indicated on a direct reading scale. A locking knob is incorporated. An attenuation range of 0 to 60 dB is provided with a VSWR of 1.15 maximum. Other specifications are shown in the table. Finish is instrument gray enamel.
