Abstract :
A magnetostatic wave filterbank consists of an array of narrowband magnetostatic-wave lines which have a common microstrip input transducer and separate output transducers. The center frequency of each channel is determined by a magnetic bias field supplied by a permanent magnet with a linear field gradient. A description is given of the construction and performance of an improved version of a 13-channel filterbank operating at S-band with a 24-MHz (3-dB) channel bandwidth and a 50-dB dynamic range. A comparison of present and projected performance data is given.<>
