1. A method of impedance matching a radio frequency switch network that includes a plurality of branches each including at least one phase change material (PCM) switch, the method including coupling each branch of the radio frequency switch network to a common terminal through a respective separate and distinct inductor corresponding to such branch, and coupling each branch of the radio frequency switch network to a corresponding separate and distinct signal terminal, wherein each branch defines a switchable signal path between the common terminal and the corresponding signal terminal.
