Abstract :
The centre-frequency conversion and reflection coefficients of a SPUDT can be deduced from the directivity if the electrical load is designed either for minimum conversion loss or for zero acoustic reflection. A 3 dB conversion loss is obtainable, with zero acoustic reflection, if the directivity is 3 dB.
