  "description": "<p>A very low-loss micromachined waveguide bandpass&nbsp;filter for use in D-band (110&ndash;170GHz) telecommunication applications&nbsp;is presented. The 134&ndash;146GHz filter is implemented&nbsp;in a silicon micromachined technology which utilises a double&nbsp;<br>\nH-plane split, resulting in significantly lower insertion loss than&nbsp;conventional micromachined waveguide devices. Custom splitblocks<br>\nare designed and implemented to interface with the&nbsp;micromachined component. Compact micromachined E-plane&nbsp;bends connect the split-blocks and DUT. The measured insertion&nbsp;loss per unit length of the waveguide technology (0:008&ndash;0:016dB=mm) is the lowest reported to date for any micromachined&nbsp;waveguide at D-band. The fabricated 6-pole filter, with&nbsp;a bandwidth of 11:8GHz (8:4%), has a minimum insertion&nbsp;loss of 0:41dB, averaging 0:5dB across its 1dB bandwidth,&nbsp;making it the lowest-loss D-band filter reported to date in any&nbsp;technology. Its return loss is better than 20dB across 85% of&nbsp;the same bandwidth. The unloaded quality factor of a single&nbsp;cavity resonator implemented in this technology is estimated to&nbsp;be 1600.</p>",
