Techniques are disclosed for increasing capacitance, decreasing losses, and/or improving a quality factor of a SAW filter. The techniques include using a partial-IDT instead of a reflector between two groups of IDTs. The partial-IDT is implemented having a cavity transition on a first end and a reflector transition on a second end. The cavity transition facilitates propagation of main-resonance acoustic waves into, or between elements of, the partial-IDT. The reflector transition facilitates reflection of main-resonance acoustic waves.
