An Analytical Study on Hairpin Type LPFs Using MSL Resonators Loaded with Dielectric Rods

This paper focuses on realizability of a reduced-size LPF using a substrate loaded width high relative dielectric constant rods by LTCC technologies. We have examined two sections form hairpin type LPF and one section form hairpin. As a result, in comparison with the characteristic of one section, we could confirm that good out-of-band characteristic was provided with the realization of a steep skirt characteristic.
