Title:
TWO-LINE OUTPUT MATCHING CIRCUIT OF INVERSE CLASS F POWER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2019/015277
Kind Code:
A1
Abstract:
A two-line output matching circuit (1) of an inverse class F power amplifier (10). The two-line output matching circuit (1) comprises a pre-matching circuit (11) and a two-line matching circuit (12). A first microstrip line (111) and a second microstrip line (112) are connected in series. Connected to a connecting line between the first microstrip line (111) and the second microstrip line (112) is a third microstrip line (113) serving as an open circuit branch. An input end of the first microstrip line (111) serves as an input end of the two-line output matching circuit (1). The two-line matching circuit (12) comprises a fourth microstrip line (121) and a fifth microstrip line (122). The fourth microstrip line (121) is connected in parallel on the fifth microstrip line (122). The input end of the first microstrip line (111) is connected to an output end of a GaN transistor (2). An input end of the second microstrip line (112) is connected to an output end of the first microstrip line (111). An output end of the second microstrip line (112) is connected to an output end of the fifth microstrip line (122). An output end of the fifth microstrip line (122) serves as an input end of the two-line matching circuit (12). This not only provides the inverse class F power amplifier (10) with high harmonic control and impedance matching functions but also with a circuit structure of increased compactness.
