Abstract
The present invention provides a semiconductor integrated circuit device and a radio frequency module realizing reduction in high-order harmonic distortion or IMD. For example, a so-called antenna switch having a plurality of transistors between an antenna terminal and a plurality of signal terminals is provided with a voltage supply circuit. The voltage supply circuit is a circuit for supplying voltage from a voltage supply terminal to at least two signal terminals in the plurality of signal terminals via resistive elements. With the configuration, antenna voltage dropped due to a leakage or the like can be boosted and, for example, transistors in an off state can be set to a deep off state.
