WebThe circular waveguide contains an iris coupled filter with as many irises as needed to produce the required filter response. Glossary Template:Glossbackaperture An opening in a wall of a waveguide or barrier between sections of waveguide through which electromagnetic radiation can propagate. Template:Glossbackcharacteristic impedance WebFor silver-plated waveguides, losses are typically 8 dB/100 m at 35 GHz, 30 dB/100 m at 70 GHz and nearly 500 dB/100 m at 200 GHz. To reduce losses, especially at the highest frequencies, waveguides are sometimes plated (on the inside) with gold or platinum. As already pointed out, the waveguide behaves as a high-pass filter.
