Title
Saw Group-Type Multistrip Coupler.
Abstract
A multistrip coupler (MSC) called the group-type multistrip coupler (GTMSC) is proposed. Several GTMSC structures are presented and their basic properties are discussed. As an application of the GTMSC, some low-loss SAW filters using two GTMSCs and two transducers are introduced. Filters of less than 10-dB insertion loss with no tuning inductor can be easily realized with excellent sidelobe rejection, little reflection ripple and 3-dB bandwidth of 1-3% on 128 degree Y-X LiNbO//3. Because the width of the GTMSCs and transducers equals 1/4 wavelength, filters of higher frequency can be fabricated.
