Integrated RF IC with quartz SAW filtering and frequency control components in a single hybrid greatly simplifying and speeding up the user's RF design task
High data rates for data, control and digitized voice transmissions
Stable, sensitive receiver technology with excellent "channel capture" performance
Ultra Low current consumption for operation from small 3 V batteries
Very small, low-profile package to make "watch size" applications practical
