Design of Second-order Inductive-coupled Resonator-based Bandpass Filter with Controllable Multiple Transmission Zeros

摘要：

　　This study proposes synthetic design for a compact LTCC bandpass filter with high rejection over a wide stopband for use in 2.4-2.5 GHz WLAN application.The presented design derives formulas for synthesizing a filter to meet the specification requirement in the passband insertion and return losses as well as the stopband attenuation.The presented bandpass filter has feedback paths for a coupling capacitor and a grounding inductor to provide controllable multiple transmission zeros at 5.0 GHz and 3.3GHz stopband,resulting in high stopband rejection in 4.8 to 5.0 GHz range and 3.2 to 4.8 GHz range,which suppresses the second harmonic band and Ultra-wideband(UWB)signals.Experiment results are very agreement with the full-wave simulation results.
