Abstract :
The authors report on the design and fabrication of an eight-pole bandpass filter based on the capacitive connection of four third-harmonic, two-pole monolithic filters using a 163° rotated Y-cut lithium tantalate substrate. The filter has a nominal center frequency of 32.5 MHz, and attains a bandwidth of approximately 0.5% of center frequency. The close agreement between the measured response and the design specifications validates the design and fabrication procedures used
