Abstract

This paper presents a thermally actuated nanocrystalline diamond micro-bridge for RF and high power applications. The diamond bridges are integrated on a CPW transmission line and small signal measurements of the actuator working as a switch are presented. The bridges are actuated at 2 volts drawing a current of 30 mA. Tunable inductors with an inductance ratio of 2.2 at 30 GHz are also presented. High power measurements in the range of 24-47 dBm for the diamond actuator in a microstrip topology are presented.
