Patent ID: 8179206

Claim:
A low-voltage control high-frequency switch comprising: a first signal line arranged between a shared signal input/output portion and a first signal input/output portion; a second signal line arranged between the shared signal input/output portion and a second signal input/output portion; a first current route in which a direct current flows, the first current route including a first diode; and a second current route in which a direct current flows, the second current route including a second diode; wherein the first and second current routes are connected in parallel at a parallel connection such that directions in which the direct currents flow in the first and second current routes substantially match each other; a single common inductor is arranged between a first node of the parallel connection and a ground; the first current route and the second current route are commonly connected to the ground by the single common inductor; a second node of the parallel connection defines a control-voltage input portion; and the first diode is arranged in series with the first signal line, and the second diode is arranged in shunt with the second signal line.
