FlexTwist® waveguide components The value of a waveguide solution is in its performance—and its precision. Your waveguide is a critical link in point-to-point and point-to-multipoint digital radio links—so measuring the value of your waveguide's performance is the same thing as measuring the value of your network itself.

In electromagnetics and communications engineering, the term waveguide may refer to any linear structure that conveys electromagnetic waves between its endpoints. However, the original and most common meaning is a hollow metal pipe used to carry radio waves.This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave It contains the waveguide table that was previously a separate download It provides a plot of waveguide loss for up to 12 different standard rectangular waveguides It has a separate page for the user to design their own waveguide, including filling it with a dielectric of their choice. losses that can be tolerated. Coaxial cables are widely used to connect RF components. Their operation is practical for frequencies below 3 GHz. Above that the losses are too excessive. For example, the attenuation might be 3 dB per 100 m at 100 MHz, but 10 dB/100 m at 1 GHz, and 50 dB/100 m at 10 GHz. the frequency band leakage loss in SIW is very high but as frequency increases it falls down to the order of other losses i,e of the order of dielectric and conductor losses and attenuation in SIW approaches to that of waveguide. It is also concluded that dielectric loss slowly increases with frequency and plays the most significant role at upper waves propagating in rectangular waveguides with finite conductivity walls. The wavenumbers kx and ky in the x and y directions respectively, are obtained as roots of a set of transcendental equations derived by matching the tangen-tial component of the electric field (E) and the magnetic field (H) at the surface of the waveguide walls
