SURFACE ACOUSTIC WAVE FILTER |
| 摘要 |
FIELD: physics. ^ SUBSTANCE: surface acoustic wave (SAW) filter has a piezoelectric acoustic line on whose surface there are input and output wideband transducers and a periodic structure in between in form of a system of ferroelectric domains with opposite polarisation, made using a laser-electrical technique and having the required resonance frequency. ^ EFFECT: increase in Q-factor to 104 and possibility of adjusting resonance frequency of the SAW filter. ^ 2 dwg |
