Fabrication of a SAW Bandpass Filter using Reddy Window Function

Reddy Window 함수를 이용한 SAW Bandpass 필터의 제작

In this part a new window function is used to design a SAW band pass filter. As an example, we selected a 99.9 MHz 20-percent bandwidth 20-dB insertion loss filter and fabricated a device on 128$^{\circ}$ X-rotated $LiNbO_3$. The theoretical predictions of a design sample are compared with the experimental data and are shown to be in good agreement over the operating range.
