| Abstract: | Low temperature co- fired ceramic（LTCC） filters with small- size, low- loss and high - attenuation are widely employed in communication and electric products application recently. In this paper, by analyzing the transmission theory of stripline, coupling- factor K and extemal Q - factor, a technique to design muhilayer LTCC bandpass filter is proposed. Finally, a bandpass filter with center frequency fo（2.45 GHz）is designed according to the proposed technique, provided with the results of its model simulation. |
