SIFW partial H-plane filter with quarter wavelength resonators |
615 |
Furthermore, the filter performances are defined purely in terms of photolithography on a planar layer. Transitions to microstrip are demonstrated allowing SIFW to be easily integrated with other planar circuits. A four-pole bandpass filter, working at X-band, is designed, fabricated using standard printed circuit board process, and measured. Superior spurious frequency response is achieved, and good agreement between the simulated and measured results is presented.
