Equivalent Circuit Design of 2.4GHz Band LTCC Bandpass Filter

2.4GHz 대역 LTCC 대역통과 여파기의 등가회로 설계

The LTCC bandpass filter using multilayer resonators is made of combline type and interdigital type parallel coupled-lines. The equivalent circuits of parallel coupled-lines are analysed. They are applied to make an equivalent circuit of LTCC bandpass filter using multilayer resonators. The 3-pole bandpass filter of the center frequency of 2.45GHz with 200Hz bandwidth is designed and fabricated. The simulated result of the bandpass filter are presented.
