Compact size cellular / GSM band pass filter with High Resistivity thin film Silicon Integrated Passive Device (IPD) technology

A compact size 800MHz band-pass filter (BPF) design fabricated with ON Semiconductor High Resistivity Silicon Integrated Passive Device (IPD) process is presented in this paper. Insertion loss <; 1.6 with reasonable filter rejection is achieved in a standard 01005 size. The proposed design provides good separation from multiple bands such as Mobile Radio, UHF low band, 2.4GHz ISM, and WiMAX applications. Here we discuss the IPD design procedure, simulation and model correlation results through on-wafer measurement. Performance variation by packaging option is also discussed.
