高频前置电路
摘要：
本发明的高频前置电路(10)包括频带开关(20)、双工器(31、32、33)以及主开关(40)。频带开关(20)包括公共端子(PC20)、选择端子(PS21、PS22、PS23)。主开关(40)包括公共端子(PC40)、选择端子(PS41、PS42、PS43)。双工器(31、32、33)被分别连接在选择端子(PS21、PS41)之间、选择端子(PS22、PS42)之间、选择端子(PS23、PS43)之间。选择端子(PS23)被设置在选择端子(PS21、PS22)之间，选择端子(PS43)被设置在选择端子(PS41、PS42)之间。频带彼此接近或重叠的第1、第2通信频带分别经由双工器(31、32)进行收发。
摘要（英）：

A high-frequency front-end circuit (10) that is provided with a band switch (20), duplexers (31, 32, 33), and a main switch (40). The band switch (20) is provided with a common terminal (PC20) and selectable terminals (PS21, PS22, PS23). The main switch (40) is provided with a common terminal (PC40) and selectable terminals (PS41, PS42, PS43). The duplexers (31, 32, 33) are respectively connectedbetween the selectable terminals (PS21, PS41), between the selectable terminals (PS22, PS42), and between the selectable terminals (PS23, PS43). The selectable terminal (PS23) is arranged between theselectable terminals (PS21, PS22). The selectable terminal (PS43) is arranged between the selectable terminals (PS41, PS42). First and second communication bands that have adjacent or overlapping frequency bands are transmitted/received via respective duplexers (31, 32).
