Abstract :
A new design method is proposed for multiple-stage combline bandpass filters made of stripline resonators. The Grayzel transformation is used for separating the adjacent coupling of each resonator and decomposing the filter into pairs of two coupled resonators. After the design is finished, identical resonators are equally spaced with auxiliary capacitors, which are of a simple structure so that they may be fabricated with a low temperature cofired ceramic (LTCC).
