Design and Implementation of LTCC Low Pass Filter

Abstract

LTCC form filters are very common at home and abroad, and their types are also varied. A low-pass filter design method is introduced. An S-band filter is simulated and designed. In the DC-3.4GHz range, S11 is greater than 20dB, 3GHz or higher, 10GHz or lower, and S21 is less than 40dB. This indicator is better than the MINI-related LTCC low-pass filter indicator. Can be used for S-band component design to filter out second and third harmonics.
