Abstract

The disclosure related to a RF front-end device, a RF system and an electronic device. The RF front-end device is configured with an antenna terminal, a control terminal for receiving multiple control signals, and multiple input terminals for receiving multiple RF signals. The RF front-end device includes: a first switch unit having multiple first terminals connected to the multiple input terminals respectively; a power amplification unit, having an input terminal connected to a second terminal of the first switch unit, and an output terminal connected to the antenna terminal; and a control unit, where the control unit is connected to each of the control terminal and the power amplification unit, and is configured to control, based on a received target control signal, the power amplification unit to perform power amplification processing on a received target RF signal. The target control signal is one of the multiple control signals, and frequency bands of the multiple RF signals are different. This can increase the multiplexing efficiency of the power amplifier unit, enhance the integration level of RF front-end device, and achieve a low cost.
