Document Type and Number:
WIPO Patent Application WO/2022/166655
Kind Code:
A1
Abstract:
Disclosed in the present application is a push-pull power amplifier, which is applied to the technical field of radio frequency circuits, and is used for solving the problem that an existing push-pull power amplifier circuit is complex in structure and occupies excessive space of a chip or a circuit board. The push-pull power amplifier comprises a conversion balun, a first bias circuit, a first capacitor, a first amplifier, and a second amplifier; the conversion balun comprises a primary coil and a secondary coil, and the secondary coil is formed by connecting a first coil segment and a second coil segment. The first coil segment and the second coil segment are connected by means of the first capacitor; a first end of the first coil segment is connected to an input end of the first amplifier; a second end of the first coil segment is connected to a first end of the first capacitor; a second end of the first capacitor is connected to a first end of the second coil segment; a second end of the second coil segment is connected to an input end of the second amplifier; the first bias circuit is coupled to the first end and second end of the first capacitor, separately.
