Due to the sophistication and diversification of information and communication networks, the communication speed is increasing. For this reason, power amplifiers used in communication devices such as smartphones are required to work at higher frequencies. Here, we discuss to increase the frequency of the envelope tracking (ET) amplifier.
The ET amplifier changes the drain voltage of the RF amplifier in response to the changing signal amplitude. This kind of operation is expected to improve the efficiency of the operation.
In this report, we focus on a method using PWM modulation and D-class amplifiers as envelope amplifiers for ET amplifiers. |
