The electro-magnetic composite materials prepared by low temperature co-fired ceramics （LTCC） technology were chosen to fabricate multilayer chip inductors, capacitances and anti-EMl filters. One used ADS and HFSS software to carry out the circuit simulation and three-dimensional structure simulation of low pass filter. Through simulating and revising the model repeatedly, one finally designed the follow LTCC low pass filters with packages size of 0805 type. The cut off frequency of filter is 50 MHz, ripple within the passband is below 0. 5 dB, attenuation exceed 20 dB at 100 MHz.
