Popis:	This paper presents an efficient method for enhancement of the operating frequen-cies of the SAW devices - use of surface transverse waves (STW) with high propa-gation velocity V = 5000 m/s on a standard piezomaterial quartz. The approaches for a realization of the STW resonators with the high quality factor and STW filters with the low insertion loss were considered. The quantitative and qualitative char-acteristics of above 1 GHz STW devices for each approach were given.
