Flexible Waveguide Diagram

Flexible waveguide use mechanically and electrically interlinked metallic structures to form a hollow channel that behaves as a waveguided with enhanced flexible and somewhat reduced performance. As the interlinked metallic structures, even if soldered and crimped, are not perfectly smooth conductive walls, the performance of flexible waveguides will not likely reach that of a traditionally manufactured waveguide. That being said, the flexible nature of these waveguide allows them to be used in applications for which rigid waveguide structures may be too bulky, unfit for the complexity of the geometries, too heavy, take too long to design/assemble, or may be unavailable during emergency repairs or retrofitting operations.

Flexible Waveguide Usage

Flexible Waveguide Usage

Flexible waveguide normally is for connecting different kinds of two components. Flexible waveguide is often together used with rigid waveguide systems especially if it cannot be located or positioned well. Flexible waveguide advantages offered is well outweigh the electrical performance limitations which is easy for flange and waveguide port change position. In other words is allow for mechanical movement.

Flexible Waveguide Benefits

Flexible waveguide are used in virtually every application that rigid waveguide are used, with the exception of extremely high power, low loss, or certain mechanical stresses are common. Waveguide systems that may require a range of adjustments, such as with satellite positioning systems, are likely to employ flexible waveguide. The bendable, and sometimes even bend/twist, nature of flex waveguide can reduce installation difficulties from misalignments common in system installation, repair, retrofitting. Flexible waveguides can also be used to isolate different sections of waveguide and mechanical structures from vibration and shock, which a rigid waveguide interconnect would not be able to do. Lastly, a flexible waveguide could be used in structures that are likely to shift or produce relative movement during thermal cycles, movement, or intense weather.

Flexible Waveguide Applications

Flexible waveguide for satellite applications and other airborne and space systems include seamless flexible waveguide, flexible twistable waveguide, flexible waveguide, and semi flexible waveguide.

Flexible and twistable rectangular waveguides are used in a wide variety of Satcom, VSAT and telecom applications that carry high frequency radio.

Flexible waveguide is often used to connect two elements using rigid waveguide systems together, especially when they cannot be accurately located or positioned.. For example, flexible waveguide is often used to connect antenna systems, especially when they may not be fixed, to the base transmitter receiver system.

Flexible Waveguide Construction

Flexible waveguide is available in a variety of different forms. Each type has its own advantages and disadvantages:

Flexible and Twistable

Flexible twistable is sealed electrically via a friction joint. This construction has the best twistable performance of all flexguides.

Flexible Waveguide

Flexible Waveguide core is wound with a solder fillet in the Interlock, thus eliminating any RF and Pressure Leakage. Flexible Waveguide will flex in the E and H planes, although pre-set twists can be incorporated during manufacture.

Flexible Seamless

Flexible/seamless offers a solution to problems where pressurization is required. It has no solder joints and therefore can easily hold pressure.

Made from helically wound silver plated brass strip

The flexible waveguide may be made from flat ribbons would on a rectangular mandrel. The edges are then convoluted or folded in and interlocked. The convoluted flexible waveguide may be left unsoldered or it may be soldered - the flexibility of the waveguide results from the flexing of each arm and not the relative sliding of the ribbons. However if it is soldered it does loose some flexibility and it is not able to be twisted to any degree.

A form of corrugated flexible waveguide may be constructed. It is manufactured by shaping thin wall rectangular tubing. It may also be made by bending and soldering corrugated sheet metal.

It is also possible to construct a bellows-style flexible waveguide using a flexible alloy.

Another common form of flexible waveguide construction is to use a helically wound system. This form of flexible waveguide is manufactured by a process of helical winding a silver coated, brass strip to form a continuous, uniform rectangular tube.

In general, flexible waveguide is jacketed in Neoprene, Silicone, Viton, Devcon or other similar materials to provide additional protection from mechanical damage while still allowing flexibility.
