Abstract :
A Ka-band diplexer using novel planar nar TE mode dielectric resonators has been developed. The resonators are manufactured with precise photolithography process on the high-dielectric-constant ceramic substrate. High unloaded-Q of 1100 is obtained at 26-27 GHz. A small-size diplexer with low loss and high attenuation characteristics is realized. This diplexer has been made within a plastic package which shows excellent thermal stability. The diplexer can be applicable to widely-expanding high-speed subscriber radio communication systems.
