A power amplification apparatus includes: an amplification unit for amplifying an RF signal, a chalk inductor which is connected between the amplification unit and an operation voltage terminal, and a resonance unit which is connected to the chalk inductor in parallel. The resonance unit forms direct resonance in a predetermined Wi-Fi frequency. A frequency usage band is a Wi-Fi frequency band. The direct resonance can be formed in a lower frequency of the Wi-Fi frequency band. |
