Patent number: 11757478Abstract: A radio frequency module includes: a module board that includes a first principal surface and a second principal surface on opposite sides of the module board; a power amplifier; and a first circuit component. The power amplifier includes: a first amplifying circuit element; a second amplifying circuit element; and an output transformer that includes a primary coil and a secondary coil. An end of the primary coil is connected to an output terminal of the first amplifying circuit element. Another end of the primary coil is connected to an output terminal of the second amplifying circuit element. An end of the secondary coil is connected to an output terminal of the power amplifier. The first amplifying circuit element and the second amplifying circuit element are disposed on the first principal surface. The first circuit component is disposed on the second principal surface.Type: GrantFiled: September 29, 2022Date of Patent: September 12, 2023Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Shigeru Tsuchida, Daerok Oh, Takahiro Katamata, Satoshi Goto, Mitsunori Samata, Yoshiki Yasutomo

Patent number: 11394353Abstract: A power amplifier circuit includes a power amplifier and an output matching circuit that includes a first capacitor and a switch unit. The first capacitor has a first end electrically connected to an output end of the power amplifier. The switch unit includes a first input terminal, a second input terminal, a first output terminal, and a second output terminal. The switch unit causes the first input terminal to be connected to the first output terminal and causes the second input terminal to be connected to the second output terminal in a first operation mode of the power amplifier, and causes the first input terminal to be connected to the second output terminal and causes the second input terminal to be open or to be connected to the first output terminal in a second operation mode of the power amplifier.Type: GrantFiled: November 18, 2020Date of Patent: July 19, 2022Assignee: MURATA MANUFACTURING CO., LTD.Inventor: Yoshiki Yasutomo
