| 内容記述 | A method is described for designing a broad-band matching network between IDT and electrical source or load, by use of only one transformer and one tuning inductor. The method is based upon both detuning the resonance frequency of the matching network and decreasing the network Q factor by the step-up transformer. Calculations show feasibility of SAW delay line having insertion loss (IL) of 2l dB, 3 dB fractional bandwidth (BW) of 55% and triple transit suppression (TTS) of 62 dB for 3 electrode (N=1) IDT. An exnerimental example shows IL=25 dB, BW-46.5% and TTS=61 dB around at 33 MHz, and confirms the theoretical predictions except for BW. The short IDT launchs spurious bulk modes and bulk longitudinal wave degrades substantially BW. | |||||
