Abstract

Multi-strip resonator BPF is fabricated in the LTCC configuration. The center frequency is 3.5GHz, fractional bandwidth is 0.1 and 3-stage Chebyshev type is designed. The relative permittivity of the ceramic is 18.3, resulting in the size as small as 2.3 × 1.6 × 0.73mm. The in-band loss is 3.5dB, which could be reduced in the stable mass production state. The spurious suppression of more than 30dB is attained up to the frequency higher than 10GHz.
