Title:
POWER AMPLIFICATION CIRCUIT, HIGH-FREQUENCY CIRCUIT, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/161928
Kind Code:
A1
Abstract:
Accordingly to the present invention, power consumption can be further reduced while accommodating high-frequencies. A power amplification circuit (1) is provided with a transmission circuit (2), a control circuit (3), a first terminal (4), and a second terminal (5). The transmission circuit (2) includes an amplification element. The amplification element amplifies the power of high-frequency signals. The control circuit (3) controls the transmission circuit (2). A serial data signal is input into the first terminal (4). The serial data signal includes information based on a serial data standard. A digital signal different from the serial data signal is input into the second terminal (5). The control circuit (3) controls the transmission circuit (2) on the basis of the digital signal input from the second terminal (5).
