Burst Processor Tapped Delay Line.
Abstract
ICS, Design, Acoustic surface wavesThe object of the program is to develop and demonstrate a doppler resolution filter configured as a tapped delay line. The device will operate at a center frequency of 220 MHz and a 50 MHz 1 dB bandwidth. The Burst Processor Tapped Delay Line geometry will use a parallel channel approach such that each delay output is derived from a separate acoustic channel. The device employs double electrodes for both input and tapping (output) transducers; the input consists of a simple, periodic transducer with six (6) double electrodes, while the outputs use novel 'phase-reversal transducers' with eleven (11) electrodes. The BPTDL also uses a 300 MHz reference channel which directly measures the time delay and controls the insertion phase by means of a temperature control system. The delay line design has been thoroughly analyzed and experimentally tested. Fabrication and evaluation of two prototype devices has been completed. (Modified author abstract)
