Multilayer LTCC technology enables RF modules to be reduced dramatically by taking advantage of the three dimensional flexibility. Compared to a conventional two dimensional PCB, LTCC allows higher density, reduced size, and lower cost. In this research, BPF based on LTCC for 900MHz ZigBee application was implemented which can replace SAW filter with using the material of the Dupont9599's dielectric constant 7.8. In the mean while the embedded inductor was optimized with the structural factors like width, shape, Rin, spacing etc. and resulting Q factor of inductor was higher than 60. The value of inductance of capacitance in LC tank resonator adequately, which resulted in the Q factor of tank circuit over than 60. And finally, band pass filter with the insertion loss below than 3dB in very narrow passband and attenuation of 20 dB at both stopband by considering the structure of series capacitor. This filter response is expected to enough for 900MHz ZigBee application.
