Flexible waveguides are structures that guide electromagnetic waves in one calibrated way with minimal loss of energy or signal strength.
Without the curtailment of waveguides, the amplitudes decrease as it traverses a three dimensional space-as stated by the inverse square law.
Often referred to by the portmanteau as “flexiguides”, they are used to connect two elements using two rigid wave guides system together, particularly when they cannot be located or positioned.
Flexible waveguides are made up of helically wound silver-plated brass strips and the required mechanical support is made available by the protective jacket. It is a thin-walled guide tube pressed to into shape to form convulsions which allow it to flex.
There are 3 main types of flexible waveguides and they are 1) Flexible and twistable 2) Flexible only and 3) Flexible/seamless.
Flexible twistable waveguides are reputed for the best twistable performance among all flexibles though is not recommended for passive intermodulation applications.
Flexible-only waveguides are wound and have a soldered interlock which obliterates RF and pressure leakage. A pre-set twist can be accommodated during its manufacturing stage.
Flexible/Seamless waveguide is used where pressurization is involved as its structure has no soldered joints, hence totally secured.
Flexible waveguides can be manufactured as straight sections that may eventually be bent into shape, as a pre-formed section to be jacketed into defined shape or hybrid sections with flexible and rigid sections.
Specific fabrication of rectangular and double ridge waveguide size is also possible if needed.
