128° rotated Y-cut Black Lithium Niobate is used as a substrate material for the creation of simple one pass SAW bandpass filters. Center frequencies between 100 and 300 MHz were designed with varying aperture widths and designed bandwidths. The S21 measurements were made with Agilent Technologies E5071C, two port network analyzer, and were compared to theory. Without considering the effects of the asymmetric coplanar waveguides (ACPW) used to connect the ground-signal-ground probes to the device under test (DUT) the average distance between measured and theoretical data is 0.523dB, near the center frequency.
