In the millimeter wave industry, waveguides are an important component that can transmit high-frequency signals from one point to another with minimal signal loss. A waveguide is a hollow metallic or dielectric structure that confines and guides electromagnetic waves within its boundaries. Its high power handling capabilities, low attenuation and low dispersion make it ideal for high frequency applications.
High-precision subtractive processing Machining using high-precision subtractive methods has been a classic method for manufacturing waveguide devices. Starting from a block of electrical conductor (usually aluminum or brass, although other metals with good conductivity can be used), the inner portion of the waveguide is carved out (usually with a drill, although, as will be discussed, other options are possible). These techniques often provide smooth surfaces on the inner walls of the waveguide, thereby reducing power losses. Furthermore, since the waveguide device is made from a metal block, it will exhibit excellent mechanical robustness.
