A high performance RF (radio-frequency) switch based on the phase change effect in germaniumtelluride (GeTe) is described. Thermal pulses applied to a separate independent thin film heating element for 0.1-1.5 μs toggles the switch in a latching fashion. Being non-volatile, no power is required to hold the switch in the on- or off-state. State-of-the-art solid-state RF switches currently in use have an on-state loss of 1 dB; here, we demonstrate an inline phase change switch with a low on-state resistance showing over a frequency range of 0-40 GHz an insertion loss of just 0.1-0.24 dB.
