Mismatch losses in multiply tapped SAW convolvers

An analysis procedure is given for calculating the output mismatch loss in a multiply tapped SAW convolver. The analysis takes into account the lossy transmission-line properties of convolvers and includes realistic values for the parasitics due to bonding pads and wires. Results illustrating trade-offs between bandwidth and insertion loss for a convolver with six taps are given, which provide guidelines for the design of broadband output matching networks.
