Abstract :
The theory of asymmetric λ/2 coupling filter is presented. According to the both coupling modes of electric and magnetic, two novel coplanar waveguide (CPW) structure filters, the center frequency is 60GHz, is obtained based on the theory of asymmetric λ/2 coupling. The harmonic suppression technology is introduced in the design process. The parasitic frequency and second harmonic are effectively suppressed by the harmonic suppression technology. The bandwidth of the electric coupling filter is 1.5GHz and the insertion loss is 0.6 dB. The bandwidth of the magnetic coupling filter is 12GHz and the insertion loss is 0.3 dB.
