Abstract :
Computer optimisation of simple matching networks to interdigital transducers using an equivalent-circuit model has been carried out. Low insertion loss and phase dispersion with wide bandwidth can be obtained even with seriously mismatched devices. The theory is verified experimentally for a 3-pair interdigital device at 30 MHz on lithium niobate.
