The band switch (20) includes a common terminal (PC20) and selection terminals (PS21, PS22, and PS23). The main switch (40) includes a common terminal (PC40) and selection terminals (PS41, PS42, PS43). The duplexers (31, 32, and 33) are connected between the selection terminals (PS21 and PS41), between the selection terminals (PS22 and PS42), and between the selection terminals (PS23 and PS43), respectively. The selection terminal (PS23) is connected between the selection terminals (PS21 and PS22) and the selection terminal (PS43) is connected between the selection terminals (PS41 and PS42). First and second communication bands the frequency bands of which are close to or overlapped with each other are transmitted and received through the duplexers (31 and 32)."},"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 (10) includes a band switch (20), duplexers (31, 32, and 33), and a main switch (40).
