無線通信装置、ドハティ増幅器及び無線通信装置の制御方法 |
摘要 |
A wireless communication apparatus includes: a first amplifier configured to amplify an input signal; a second amplifier configured to amplify the input signal when an input level of the input signal is equal to or larger than a given level; an impedance converter configure to switch an load impedance of the first amplifier and output a composite output of an output from the first amplifier and an output from the second amplifier; an impedance controller section configured to control a switching of the load impedance of the first amplifier based on a bandwidth of the input signal; a distortion compensation section configured to perform distortion compensation of the input signal and supply a compensated input signal to the first amplifier and the second amplifier; and a filter section configured to limit a band of a signal output from the impedance converter. |
