Document Type and Number:

WIPO Patent Application WO/2021/241474

Kind Code:

A1

Abstract:

According to the present invention, power consumption is reduced. This tracker module (1) comprises: a second substrate separate from a first substrate; a tracker component (3); and a low-pass filter (4). A power amplifier is disposed on the first substrate. The tracker component (3) supplies a power supply voltage to the power amplifier. The low-pass filter (4) is connected onto the path between the output end of the tracker component (3) and the power amplifier. The tracker component (3) and the low-pass filter (4) are disposed on the second substrate.
