Compact Magnetostatic Wave Channelizer

Abstract
A compact 5 channel filter bank is described which uses the new technology of magnetostatic forward volume waves propagating in narrow epitaxial yttrium iron garnet strips. Results are presented showing S-band performance where a -55 dB out-of-band level is achieved and a 2 tone intermodulation level rejection of 50 dB at 25 MHz from the mid-band frequency.
