Abstract

It this paper the multilayer chip band pass filter for next generation mobile communication phone is fabricated and designed. For the design the multilayer chip filter of non-contented equivalent circuit and contented equivalent circuit with attenuation pole is presented. Finally it is fabricated and designed using the multilayer chip filter of contented equivalent circuit with attenuation pole. The size insertion loss center frequency and band width of multilayer chip filter are 4.5$\times$3.2$\times$2.0[mm], 3.0[d.B] and 1945$\pm$25 MHz respectively. The multilayer chip filter was fabricated by screen printing with Ag electrode after tape casting. Simulation results of multilayer chip filter are compared with experimental results and found to be in excellent agreements.
