LTCC Bandpass Filter with Transmission Zeros Using Grounding Inductor for RF Applications
This paper proposes a third-order bandpass filter using low temperature co-fired ceramic (LTCC) technology. The filter employs two grounding inductors, connecting the two parallel LC resonators, to provide a transmission zero in the upper stopband. A feedback capacitor between input and output is also used to generate two transmission zeros. With the help of stepped-impedance resonators (SIRs), the proposed filter has a compact size of 2.5mm×2.0mm×0.9mm. The insertion loss is less than 1.3dB from 2.40GHz to 2.50GHz in passband.
