What is a Waveguide?

Waveguides are metallic lines, similar in fashion to transmission lines, which are used at microwave frequencies. They are typically utilized to connect receivers and transmitters with antennas.

Waveguides can be used instead of coax lines. There are several advantages to this:

A waveguide is completely shielded.
Waveguides have no trouble transmitting extremely high peak powers.
The waveguide has an almost non-existent loss at microwave frequencies.

Waveguides can also be pressurized with special gases to increase maximum power levels. They are typically lined with silver plating to cut down on the resistance loss, which makes your average copper or aluminum waveguide that much more efficient.

Waveguide Components

There are various waveguide components, including isolators, mixers, loads, attenuators, amplifiers, and circulators. Because is it inefficient to make a three part splitter, if you require for a signal to be split, the proper way to do it would be to use a magic tree.

Another useful waveguide component is the flexible waveguide. This item comes in handy when you need to connect two waveguides that don’t exactly fit one another. As the name implies, the flexible waveguide will make an adjustable fit between the two pieces. This is great in a pinch, although choose wisely, as some are more flexible than others.
