Patent attributes
A high-frequency power amplifying module is provided for a communication device that simultaneously uses at least a radio wave in a first band and a radio wave in a second band, and a first high-frequency power amplifier for the first band and a second high-frequency power amplifier for the second band are mounted. The first band and the second band are frequency bands that produce intermodulation distortion of a frequency included in the receive frequency band of the second band, due to a transmit frequency of the first band received by the first high-frequency power amplifier and a transmit frequency of the second band received h the second high-frequency power amplifier. The second high-frequency power amplifier includes a filter that blocks a signal at the transmit frequency of the first band.
