Abstract
An electrochromic (EC) switch is disclosed and claimed. The EC switch includes an EC region and an electrolyte region separated by a dielectric region on a ground plane. A microstrip configured to transmit an RF signal is adjacent to and in electrical contact with the EC region. A conductive pad is adjacent to the electrolyte region and a bias line couples the microstrip to the electrolyte region. Voltages applied between the ground plane and the conductive pad and between the conductive pad and the bias line switch the microstrip. The EC switch may be incorporated within a wide variety of RF devices, for example, attenuators, phase shifters and antennas.
