  • Abstract
    Measurements of acoustic-surface wave propagation losses in air have yielded the following for GaAs at 1 GHz: 3.62 dB/¿s for the [211] cut, [111] propagating orientation, and 4.22 dB/¿s for the [110] cut, [100] propagating orientation. Air loading for these two cuts is 0.27 and 0.40 dB/¿s, respectively. These results are independent of surface quality for defects up to 0.04 wavelengths in size.
