Abstract :
A GHz SAW device with two face-to-face interdigitated transducers (IDTs) was fabricated on self-standing semi-insulating GaN substrate. Using an advanced e-beam lithographical techniques, the IDTs with 0.5μm wide fingers and spacing have been fabricated on self-standing GaN substrate. On wafer measurement of the S parameters have demonstrated the operation at approximately 2 GHz with 10dB insertion loss.
