Title:
TRACKER CIRCUIT AND TRACKING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/063006
Kind Code:
A1
Abstract:
A tracker circuit (1A) comprises: an output switch circuit (30) that is configured to selectively output at least one of a plurality of discrete voltages to a power amplifier (2A); a voltage supply path (P41) that connects the output switch circuit (30) and the power amplifier (2A); and a filter circuit (40A) that is connected to the voltage supply path (P41). The power amplifier (2A) is configured to amplify a high frequency signal (RFA) of a band (A) to which a TDD is applied. The filter circuit (40A) is not series connected to but connected in shunt with the voltage supply path (P41).
