高频模块
Abstract:
上述第一分波电路配置在上述第一放大电路与上述第二分波电路之间。在这样的电路的配置中，由于第一放大电路与第二分波电路在空间上夹着第一分波电路，所以不容易在从第一放大电路到第一分波电路的路径与经由第二分波电路的从第二天线端子到第二接收端子的路径之间的空间产生耦合(电磁场耦合以及静电耦合)。结果，即使产生第一收发部的发送信号的二次谐波且包含于第二分波电路的通频带的二次谐波，高频模块也由于不容易在该空间产生耦合，而能够抑制该二次谐波的向第二接收端子的泄漏，能够使第一频带以及第二频带的隔离特性提高。
Abstract(English):

A radio-frequency module includes a first transmitter-and-receiver that transmits and receives a signal in a first band, and a second transmitter-and-receiver that transmits and receives a signal in a second band higher than the first band. The first transmitter-and-receiver includes a first amplifier circuit and a first separator circuit and the second transmitter-and-receiver includes a second amplifier circuit and a second separator circuit. The first separator is located on a substrate between the first amplifier circuit and the second separator circuit, such that the first separator circuit is spatially interposed between the first amplifier circuit and the second separator circuit.
