Abstract: A complete and effective design is introduced to realize the 0805 size of standard packaging laminated low pass filter (LPF) using the technology of low temperature co-fired ceramic (LTCC). The three-stage laminated LPF with 200 MHz cut-off frequency is successfully manufactured using the ceramic green tape with relative permittivity of 14 and tape-casting thickness of 25 μm. Testing results show that the three-order LPF sample can achieve a 3 dB return loss at 200 MHz and a 26 dB return loss at 500 MHz by Agilent 8722ES. And the measured results agree well with the simulated data. This method illustrates a way to resolve the consistency problems between simulation and manufacture.
