WebAug 17, 2024 · All filters that have the same property are called “linear phase” filters. This means that if you plot their phase shift as a function of the signal frequency, you get a straight line. Or, more precisely, a sawtooth because the phase is rolling back every 360 degrees (2π radian), but each segment of the sawtooth has the same slope.

WebGenerally, term “CRF/DMS” may refer to very different structures, including more complicated mode structures than “double mode”. It is interesting to look inside a simple 2-IDT structure which we obtain by introducing a gap in the middle of a synchronous resonator. Such a “hiccup” [7] resonator was mainly used on ST-quartz. Fig. 3. WebSAW resonators may also be multi-mode with multiple transducers and multiple reflectors, which allows a rich filter design palette. SAW resonator filters are generally much narrower band than transversal filters, and have much lower insertion loss, but have non-linear phase and are more limited in shape factor.
