Title:
HIGH-FREQUENCY CIRCUIT, TRACKING CIRCUIT, AND ELECTRIC POWER AMPLIFICATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/120086
Kind Code:
A1
Abstract:
This high-frequency circuit (1) comprises an electric power amplification circuit (10), and a tracking circuit (50) connected to the electric power amplification circuit (10). Upon receipt of a control signal (CTL1) indicating a first power class defined using a highest electric power equal to or greater than a prescribed highest electric power, the tracking circuit (50) supplies a power supply voltage (VAPT) in an APT mode to the electric power amplification circuit (10). Upon receipt of a control signal (CTL2) indicating a second power class defined using a highest electric power less than the prescribed highest electric power, the tracking circuit (50) supplies a power supply voltage (VET) in an ET mode to the electric power amplification circuit (10).
