Abstract

This paper presents novel structure of the dielectric waveguide filter suitable for reflow soldering at millimeter wave frequencies. The filter is made of crystalline quartz, and given new 110 terminal structure. The measured unloaded quality factor of the dielectric waveguide resonator made of crystalline quartz is 1470 at 60-GHz band. The fabricated 4-pole bandpass filter consisting of the resonator and the new 110 terminal structure shows good performance. The measured maximum insertion loss in the passband of the filter with bandwidth of 1GHz is 1.5 dB.
