Abstract :
New surface mountable ceramic filter for wireless communication systems has been considered. The high permittivity ceramic filling of the basic triple-mode waveguide cavity makes the proposed filter physically small. Integrated microstrip-to-ceramic-filled-waveguide transitions provide effective coupling between the cavity and planar circuit As an application example, a three-pole L-band filter with advanced high-quality factor is demonstrated
