VOx‐Based Non‐Volatile Radio‐Frequency Switches for Reconfigurable Filter

open access: yesAdvanced Science, EarlyView.
Vanadium oxide‐based memristor devices achieve high performance for next‐generation non‐volatile memory and RF switches. These devices demonstrate a cutoff frequency of ≈4.5 THz, low insertion loss (<0.46 dB), and high isolation (>20 dB) from 0.1 to 20 GHz with stable operation extended to 67 GHz.
