Low-loss SAW bandpass filter
Abstract
A SAW filter with an insertion loss of 3 dB and a reduction of not less than 30 dB in the sidelobe of the amplitude frequency response is described. The filter was constructed on the basis of a transducer with capacitive weighting of the electrodes and sectioned unidirectional transducers.
