Rich Ruby

Rich started FBAR in 1992/1993 and soon after invented the all-silicon microcap FBAR filters for size reduction and quality purposes. Rich has ridden the commercial success of ultra-miniature filters from the early days of flip phones (where size mattered), the exciting days of ‘Feature’ phones (few rf bands but demanding high performance) and finally to the current Smart phone era (added complexity of carrier aggregation, demand for increased rf power and large filter count). Since ~2016, he has worked to become self-taught in SAW using generalized resonator technology built up on FBAR. The purpose is to better understand the potential of surface wave technology versus bulk wave devices and explore areas where both technologies can complement each other. Rich has many patents on FBAR, SAW technology and most recently RFFE system level patents.
