Surface magnetostatic wave filters with magnetron sputtered nanoscale films of yttrium iron garnet

Results of operation of MSSW filters with nano-scale films of yttrium iron garnet are presented. The peculiarities of filter characteristics are discussed. Nanoscale films in MSSW filter are used for broadening of input signal dynamical range due to the realization of single domain state in YIG films even at low magnetic field 1E. The use of nanoscale YIG films in MSSW filters allows increasing of frequency selective characteristics of these devices in the decimeter microwave range. MSSW filters with films grown by the magnetron sputtering have low insert losses in comparison with films grown by LPE.
