<p>A power amplification apparatus and a radio device, comprising a power divider, a carrier frequency amplifier, a peak amplifier and a microstrip line. The input ends of the carrier frequency amplifier and peak amplifier are connected to the output end of the power divider respectively, both the output end of the carrier frequency amplifier and the output end of the peak amplifier are connected to the input end of the microstrip line, and an air microstrip line is adopted for the connection between the output end of the peak amplifier and the input end of the microstrip line. The above technical solution that an air microstrip line is adopted in a power amplification apparatus can better facilitate the PCB layout and the power combination of a carrier frequency amplifier and a peak amplifier in a Doherty power amplifier and reduce the differential loss, thus realizing high efficiency and high linearity of power amplification more easily.</p> |
