The architecture, operation, and performance of a new integrated acoustic RF channelizer are described. The all- acoustic device uses a phased array piezoelectric transducer to generate frequency dispersed bulk acoustic waves over a 500 MHz bandwidth. The waves are focused onto a 25 channel receiver electrode array by a cylindrical reflector formed on the opposing surface of the device. This channelizer has the potential of providing higher dynamic range than competing technologies. © 1986 SPIE.
