1. A radio-frequency switching module comprising:
a packaging substrate configured to receive a plurality of components; and
a die mounted on the packaging substrate, the die having a switching circuit that includes a plurality of switching elements in series to form a signal branch between a first terminal and a second terminal, and a plurality of switching elements in series to form a shunt branch between the second terminal and ground, the shunt branch having an orientation relative to the signal branch, the switching elements of the shunt branch having a non-uniform distribution of a first parameter determined based in part on the orientation of the shunt branch relative to the signal branch, the non-uniform distribution determined to decrease toward the second terminal based on the orientation of the shunt branch being 180° relative to the signal branch and determined to increase toward the second terminal based on the orientation of the shunt branch being 0° or 90° relative to the signal branch, the second terminal dimensioned to support the signal branch and the shunt branch.
