Abstract
Disclosed is an iris waveguide switch capable of efficiently transmitting and switching a signal between two desired inputs and two desired outputs in high power applications, which is generally used in various applications such as millimeter wave radar, satellite systems and RF test setup. The iris waveguide switch includes two main parts: an inner cylinder and an outer cube. Periodic irises prevent the signal propagating through the gap between the inner cylinder and the outer cube to the side surface of the inner cylinder, guiding the signal into the inner cylinder bend. The inner cylinder, rotated by a drive mechanism, switches the incoming signal between two inputs and two outputs.
Claims2
A waveguide switch comprising:
- an inner cylinder adapted to switch an incoming signal by rotation between a pair of inputs and a pair of outputs, said inner cylinder having a first inner cylinder bend and a second inner cylinder bend machined therein and adapted to selectively allow propagation of the incoming signal between the pair of inlets and pair of outlets;
- an outer cube enclosing said inner cylinder, said outer cube fixing a position of the pair of inlets and a pair of outlets of said inner cylinder, said outer cube having four ports formed therein and adapted to align with the first inner cylinder bend and the second inner cylinder bend of said inner cylinder, the four ports comprising a pair of inputs and a pair of outputs, the incoming signal entering at least one of the pair of inputs and exiting at least one of the pair of outlets;
- and
- a plurality of irises positioned on an outer side of said inner cylinder and adapted to prevent the propagation of the incoming signal from a gap between said inner cylinder and said outer cube to a side surface of said inner cylinder and adapted to direct the incoming signal to at least one of the first inner cylinder bend of the second inner cylinder bend.
