Webjunction, and junction and filter dimensions are iteratively optimized according to given diplexer specifications. A conventional E-plane T-junction diplexer with inductive-iris filters in reduced-height waveguide technology and matching transformers to WR75 waveguide at all three ports is shown in the inset of Fig. 3. The performance computed with 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.
