Measurements of the Complex Impulse Response of Two-Port SAW Resonators
Measurements are reported on the impulse response of two-port SAW resonators, concerning the non-classical decay of their impulse response envelopes. Network analyzer frequency response data on 90 MHz and 674 MHz SAWR's were used with 401 point inverse discrete Fourier transform (IDFT) software to calculate these patterns. As well, impulse responses were directly obtained using a 1 GHz sampling scope. on the impulse response envelope is explained in terms of (a) power loss per transit through an effective cavity length Lce, (b) the qroup delay 1: With this technique, time-gated IDFT responses can also be applied to S- frequency response data, to obtain a measure of #e frequency response of the SAW grating r eflectors. The observed periodic ripple
