SAW integrated modules for 800-MHz cellular radio portable telephones with new frequency allocations
Several technologies are developed to achieve broader band surface-acoustic-wave (SAW) filters for portable telephones used in an 800-MHz wideband (25-MHz) cellular radio system. The design and realization of a transmitter final stage filter (high-power filter) and a prefilter (high-performance filt...
