Abstract
According to one embodiment, a radio frequency switch of a Single-Pole-n-Throw (SPnT) type includes a first RF terminal, a second RF terminal, a single RF common terminal, first MOS transistors, termination resistors, and second MOS transistors. The first MOS transistors are respectively provided between the first RF terminal and the RF common terminal and between the second RF terminal and the RF common terminal. Each of the termination resistors is configured to be connected to the first RF terminal or the second RF terminal in a selected state where a corresponding one of the first MOS transistors is in an OFF state. The second MOS transistors are connected in parallel to the respective termination resistors, and each of the second MOS transistors is configured to be controlled in a same manner as a corresponding one of the first MOS transistors.
