    • A module for a mobile radio device is proposed, whose central element is a multiswitch MS, which, as desired, can connect outputs for transmission and/or reception branches SZ, EZ of different mobile radio systems to an antenna ANT. The module is suitable for a multiband operation and, optionally, additional multimode operations and includes at least one pair of outputs for transmission and reception branches of a frequency duplexed mobile radio system. Between each output of the multiswitch and the antenna, a matching element is provided, which allows an electrical matching of the branches to be connected to it. The duplex operation is carried out via separate transmission and reception filters, or on the switch via separate outputs for transmission and reception branches.
    • 提出了一种用于移动无线电设备的模块,其中心元件是多开关MS,其可以根据需要将不同移动无线电系统的发送和/或接收分支SZ,EZ的输出连接到天线ANT。 该模块适用于多频带操作和可选地附加的多模操作,并且包括用于频率双工移动无线电系统的发射和接收分支的至少一对输出。 在多开关的每个输出和天线之间,提供了匹配元件,这允许分支的电气匹配连接到它。 双工操作通过单独的发送和接收滤波器或在交换机上通过用于发送和接收分支的单独输出来执行。

    • A functional block of a front-end circuit for a communication device, which is employed for multi-band and/or multi-mode operation, is proposed. By positioning, according to this invention, a pin diode switch in one of the parallel signal paths instead of positioning it on the input side before separating the signal paths, it is possible to do without an impedance transformation network on the input side and to thus reduce the signal loss and the space requirement of the circuit. In a further configuration, the signal paths preferably associated with the adjacent frequency bands are combined on the output side, whereby the further processing of the signals corresponding to the different frequency bands takes place in one path. This for example allows a chip set designed for (n−1) frequency bands to be used in a transmission system designed for n bands. Another embodiment of this invention enables monitoring of the received signal of a system even during operation of the other mode in a multi-mode system. Stable electrical properties of the circuit can be achieved according to this invention through integration of all components of the front-end circuit in one module.
    • 提出了用于多频带和/或多模式操作的用于通信设备的前端电路的功能块。 根据本发明,通过在分离信号路径之前定位一个并行信号路径中的pin二极管开关,而不是将其定位在输入侧,可以在输入侧没有阻抗变换网络,并因此 降低电路的信号损耗和空间要求。 在另一配置中,优选地与相邻频带相关联的信号路径被组合在输出侧,由此对于不同频带的信号的进一步处理在一个路径中进行。 例如,允许为(n-1)个频带设计的芯片组用于为n个频带设计的传输系统。 本发明的另一实施例即使在多模式系统中的其他模式的操作期间也能够监视系统的接收信号。 通过将前端电路的所有部件集成在一个模块中,可以实现根据本发明的电路的稳定的电性能。
