摘要:
A gap‐coupled InSb/LiNbO3acoustoelectric convolver has been fabricated and tested at 77 K. The results suggest the possibility of using a similar structure with a high‐density InSb diode array as an acoustically scanned infrared imaging device. Measurements indicate that near optimum bias, the convolution efficiency was −63 dBm, the convolution output was uniform along the device length to within 1.5 dB, the insertion loss was 26 dB, the 1‐dB compression point occurred at 18 dBm power input, and the efficiency was constant to ⩽ 3 dB over the range 66–70 MHz.
