RADIO-FREQUENCY POWER AMPLIFIER DEVICE AND WIRELESS COMMUNICATION DEVICE INCLUDING THE SAME
First Claim
1. A radio-frequency power amplifier device which amplifies power of high-frequency signals for communication modes including a first mode and a second mode which is a communication method different from the first mode, said radio-frequency power amplifier device comprising:
- a first input terminal to which a first radio-frequency signal for the first mode and within a first frequency band and a third radio-frequency signal for the second mode and within the first frequency band are selectively provided;
a second input terminal to which a second radio-frequency signal for the first mode and within a second frequency band and a fourth radio-frequency signal for the second mode and within the second frequency band are selectively provided, the second frequency band being different from the first frequency band;
a first power amplifier unit configured to amplify the first radio-frequency signal provided to said first input terminal;
a second power amplifier unit configured to amplify the second radio-frequency signal provided to said second input terminal;
a third power amplifier unit configured to amplify the third radio-frequency signal provided to said first input terminal; and
a fourth power amplifier unit configured to amplify the fourth radio-frequency signal provided to said second input terminal,wherein said first to fourth power amplifier units are arranged in order of said first power amplifier unit, said second power amplifier unit, said third power amplifier unit, and said fourth power amplifier unit.

Abstract
A radio-frequency power amplifier device includes an input terminal for which a first radio-frequency signal for a CDMA mode within a first frequency band and a third radio-frequency signal for a TDMA mode within the first frequency band are selectively provided, a second input terminal for which a second radio-frequency signal for a CDMA mode within a second frequency band and a fourth radio-frequency signal for a TDMA mode within the second frequency band are selectively provided, a first power amplifier unit which to amplifies the provided first radio-frequency signal, a second power amplifier unit which amplifies the provided second radio-frequency signal, a third power amplifier unit which amplifies the provided third radio-frequency signal, and a fourth power amplifier unit which amplifies the provided fourth radio-frequency signal. These power amplifier units are arranged in order of the first power amplifier unit to the fourth power amplifier unit.
