Title:
RADIO FREQUENCY POWER AMPLIFIER WITH HARMONIC CONTROL CIRCUIT AS WELL AS METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2019/200532
Kind Code:
A1
Abstract:
Radio frequency power amplifier with harmonic control circuit as well as method for manufacturing the same are disclosed. According to an embodiment, a radio frequency power amplifier includes: a planar dielectric substrate (60), a first conductive layer (61) and a second conducting layer (62). The first conductive layer (61) is disposed on a first side of the planar dielectric substrate (60). The second conducting layer (62) is disposed on a second side of the planar dielectric substrate (60). The first conductive layer (61) has a pattern comprising one or more harmonic control circuits (51). The second conductive layer (62) acts as a ground plane. The second side of the planar dielectric substrate (60) is opposite to the first side of the planar dielectric substrate (60).
