    • 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。
