Optimization design and simulation for a band-pass-filter with IPD technology for RF front-end application

Abstract

A band-pass-filter (BPF) based on silicon substrate was designed and simulated. Different software was applied to design and simulate the character of the filter. A three-order filter was designed dedicating to range 2.4 GHz-2.5 GHz use. The ideal topology circuit was designed with passive inductors and capacitors. Moreover, the integrated passive devices (IPDs) were modeled and simulated with thin film process. To enhance the performance of the IPD, some typical factors were considered to optimize the physical model. The IC design tool and electromagnetic simulation software were used and compared to analysis the character of the filter, which demonstrated that the BPF can be applied to RF front-end system.
