The multi-band amplifier amplifies high-frequency signals in a plurality of communication bands. The communication band selection circuit is connected an output end of the multi-band amplifier. The communication band selection circuit includes a communication band selection switch. The high-frequency processing circuit is connected between a first connection line connecting the multi-band amplifier and the communication band selection circuit and a ground potential. The high-frequency processing circuit includes a passive element and an impedance selection switch. The passive element is connected between the first connection line and the ground potential. A first terminal of the impedance selection switch is connected to a second connection line connecting the passive element and the first connection line, and a second terminal of the impedance selection switch is connected to the ground potential."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-frequency front-end circuit","description":"A high-frequency front-end circuit includes a communication band selection circuit, a high-frequency processing circuit, and a multi-band amplifier.
