Изобретение относитс  к радиотехнике, может быть использовано в волноводах и измерительных схемах СВЧ.The invention relates to radio engineering, can be used in waveguides and microwave measuring circuits.

Известен управл емый СВЧ аттенюатор, содержащий отрезок волновода, ферритовый стержень с поглощающим слоем, установленный вдоль оси волновода, и обмотку управлени .A known microwave controlled attenuator comprising a waveguide section, a ferrite rod with an absorbing layer installed along the waveguide axis, and a control winding.

Цель изобретени  - уменьшение габаритов и расширение функциональных возможностей управл емого СВЧ аттенюатора - достигаетс  тем, что в предлагаемом аттенюаторе поглощающий слой внутри ферритового стержн  винтообразно скручен вдоль оси волновода .The purpose of the invention is to reduce the size and expand the functionality of a controlled microwave attenuator - achieved in the proposed attenuator, the absorbing layer inside the ferrite rod is helically twisted along the axis of the waveguide.

На чертеже изображен предлагаемый аттенюатор в продольном разрезе.The drawing shows the proposed attenuator in longitudinal section.

Внутри отрезка 1 волновода пр моугольное или круглого сечени  расположен ферритовый стержень 2, а внутри стержн  - ъи ообразко скрученный .поглощающий слой 3. Поверх отрезка волновода намотана обмотка управлени  4.Inside segment 1 of the waveguide, a ferrite rod 2 is rectangular or round, and inside the rod there is an absorbing layer 3. A control winding 4 is wound over the waveguide section.

Винтообразное скручивапие поглощающего сло  эквивалентно приложению к ферритовому стержню внешнего магнитного пол  определенной величины и направлени . Совместное действие пол  намагничивани , создаваемого током обмотки и скрученного сло , приводит к усилению затухани  СВЧ мощности п по влению свойства невзаимности, что дает возможность использовать аттенюатор иThe helical twist of the absorbing layer is equivalent to applying an external magnetic field of a certain size and direction to the ferrite rod. The combined action of the magnetization field created by the current of the winding and the twisted layer leads to an increase in the attenuation of the microwave power and the appearance of the nonreciprocity property, which makes it possible to use an attenuator and
