Circuilar waveguide iris filter
WebFigure 1 shows the performance of the regular circular waveguide iris filter. Its length from first to last iris is 131.5 mm with 1 mm thick irises (cf. Table 1). It is observed that the main passband is well represented but a second wider passband appears already at 15.5 GHz, thus limiting the applicable bandwidth of such a design. WebThe circular waveguide contains an iris coupled filter with as many irises as needed to produce the required filter response.

Microwave Theory Tech., 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.
