MEMS Digital Tuning Structures

WiSpry process and design library methodology have laid the foundation for a range of innovative and highly integrated RF devices built around our core MEMS technology. At the heart of WiSpry's product innovations is our high performance Digital Capacitor technology based around common MEMS structural elements.

The Digital Capacitor concept takes these advantages to the next level. The design permits the creation of a high density, switched capacitor array, delivering a precise range of capacitor values, which in turn enables a wide tuning range to be achieved. Complementing this innovation, our high performance RF interconnect and RF transmission lines ensure that extremely high Q, low loss designs can be realized.
