description Provided are a power amplifier circuit and a communication device that improve a power handling capability required for a filter while increasing output power. A power amplifier circuit includes: an amplifier unit that amplifies an input signal of a time division duplex scheme and outputs a signal to a signal path and a signal to a signal path; a filter that is provided in the signal path and outputs a signal based on the signal; a filter that is provided in the signal path and outputs a signal based on the signal; and a transformer that is connected to the signal path through the filter and connected to the signal path through the filter and outputs an output signal based on the signal and the signal to a signal path.
