    • For use in digital optical telecommunication systems, optical semiconductor components are shown having a transition region for the expansion of the mode field of a light wave in order to reduce losses when coupling to an optical fiber or an optical waveguide of a supporting plate. An optical semiconductor component contains a deep ridged waveguide (RIDGE) with a cover layer (DS) disposed on a substrate (SUB.) The ridged waveguide (RIDGE) has a first (MQW) and second (BULK) waveguide cores, these being separated by a separating layer (SEP). The thickness of this separating layer increases in a transition region (UB1) along a longitudinal direction (L) of the ridged waveguide (RIDGE), thus increasing the vertical distance between the two waveguide centers (MQW, BULK).

    • A radio receiver for receiving radio frequency (RF) signals includes an analog down-converting and filtering section for down-converting and selecting the RF signals to an intermediate passband and a stopband which substantially determine the widest bandwidth of operation of the radio receiver. An analog-to-digital converter converts the intermediate frequency signal to a sampled digital signal. A digital filtering section, responsive to the sampled digital signal, includes wideband and narrowband digital filters for providing wide bandwidth and narrow bandwidth baseband quadrature output signals for the widest bandwidth of operation and a narrow bandwidth of operation at a frequency within a passband. The wideband digital filtering is designed to only provide a modest amount of additional stopband attenuation with a significantly sharper transition band rolloff from passband to stopband. When this limited digital filtering is applied to the signal that has already been subjected to the analog filtering, the selectivity of the overall receiver frequency response is improved. The receiver may be used for multi-bandwidth operation by simply adding digital filtering to define any narrower passband of interest. This allows bandwidth switching to take place without any changes to the analog circuitry. Simultaneous processing of both wide and narrow modes of operation may be done in the digital signal processor (DSP) performing the digital filtering.
    • 用于接收射频(RF)信号的无线电接收机包括模拟下变频和滤波部分,用于将RF信号下变频和选择为中间通带和基本上确定无线电接收机的最宽工作带宽的阻带。 模数转换器将中频信号转换为采样的数字信号。 数字滤波部分响应于采样的数字信号,包括宽带和窄带数字滤波器,用于提供宽带宽和窄带宽基带正交输出信号,用于最宽的操作带宽和通带内频率下的窄带宽工作。 宽带数字滤波被设计为仅提供适度的附加阻带衰减,具有从通带到阻带的明显更清晰的过渡带滚降。 当该受限数字滤波被应用于已经经过模拟滤波的信号时,整体接收机频率响应的选择性得到改善。 接收机可以通过简单地添加数字滤波来定义任何较窄的感兴趣的通带来用于多带宽操作。 这样可以实现带宽切换,而不会改变模拟电路。 可以在执行数字滤波的数字信号处理器(DSP)中进行宽和窄操作模式的同时处理。
