摘要
For the purpose of decreasing intermodulation distortion, a new multi-hannonic suppression band-pass filter based on a microstrio radial stub is studied. Compared with traditional resonator filters, the new filter can suppress the second, third, and even fourth harmonics directly The dimension of the filter is about 0.3 lambda(g0) x 0. 13 lambda(g0) (lambda(g0) is the guiding wavelength at the resonant frequency). Only one gap was introduced, so lower insertion loss can be obtained. Basic agreement between the measured and simulated results has been achieved.
