Abstract :
New types of SAW filter called “extended SAW resonator coupled filter” using different substrates have been developed for 800 MHz cellular systems. Design and synthesis procedure for new SAW filters are discussed. Experimental frequency responses and temperature characteristics are also given for the filters used in an antenna duplexer of ETACS, EAMPS, and NTACS cellular systems
