An electric field tunable microwave bandpass filter based on ferromagnetic resonance (FMR) in a bilayer of yttrium iron garnet and lead zirconate titanate has been designed and characterised. The filter tunability is accomplished through magnetoelectric coupling that manifests as a shift in the FMR. Studies on a microstripline filter show a 125 MHz tuning range for E=0–3 kV/cm and an insertion loss of 5 dB at 6.5 GHz.
