Abstract
A new type of an RF channelizer-filter has been developed at 20-90 MHz. The filter topology is derived from an electrical-mechanical analogy of the mammalian cochlea. The channelizer response retains the desirable features of the cochlea including multiple-octave frequency coverage, a large number of output channels with constant fractional bandwidth, and a high-order upper stop-band response. Results of a 20-channel, 20-90 MHz channelizer prototype are presented and agree well with theory.
