Not Available The development of compact and high performance ceramic filters is very important for size-limited applications. Paratek has advanced technology to significantly decrease the dielectric losses of ferroelectric materials while maintaining dielectric constants of 100 to 3000 at microwave frequency ranges. Paratek proposes to develop and fabricate a five-1/4-coaxial ceramic resonator filter, 1.5x1.0x0.5 cm with a brick-wall, high rejection response at frequencies above 1GHz by using our developed high dielectric constant (300-400) and high-Q (10000) BaSrTiO3-MgO based ceramics. The high dielectric constant material will reduce the resonator size, therefore more resonators can be put into a ceratain size volume. The increased number of resonators will improve the rejection response performance of the filter. For Phase I, a proof-of-concept filter will be delivered based on the existing and newly developed materials. The improvement of the materials will focus on the temperature stability of the materials. For Phase II, the filter will be fabricated based on the newly developed material.
