Abstract
Designs of new compact filters using cross-coupled resonators are presented. The square shape resonators require only 40% of the area of folded open loop half-wavelength resonators. The filters were designed for the 900 MHz band of the mobile communications systems (GSM, GPRS, etc.). The cross coupling provides a better filter skirt for a higher selectivity. The effect of the resonator finite quality factors was confirmed for the cross-coupled filters.
