    • A device for dynamic impedance matching between a power amplifier and an antenna, having a circulator (210), which routes a signal received from the power amplifier (10) at a first port via a second port to the antenna (30) and diverts the signal reflected at the antenna (30) and received at the second port through a third port; and a controllable matching network (24, 240, 250); is characterized in that a directional coupler (200) diverts a proportion of the signal traveling from the power amplifier (10) to the antenna (30), from which the magnitude and phase of the signal may be derived, to a signal detector (220); and the circulator (210) routes the entire signal reflected at the antenna (30) into the signal detector (220); wherein the signal detector (220) passes the magnitude and phase of both the signal traveling to the antenna (30) and the signal reflected at the antenna (30) to a controller (230), which evaluates the information received from the signal detector (220) in order to determine the present impedance value of the antenna (30) and to correct the controllable matching network (24, 240, 250) having active and passive components in accordance with the determined impedance value of the antenna (30).

    • A capacitor device, an electronic circuit comprising a capacitor device, an electronic component, and a method of forming a capacitor device are described. In the capacitor device, a current-path region extends from one of two trench capacitor electrodes to a respective contact structure. The current-path region is obtainable by thinning the substrate from an original substrate thickness down to reduced substrate thickness either in a lateral substrate portion containing the capacitor region or over the complete lateral extension of the substrate before forming the first and second contact structures. The capacitor device exhibits a reduced impedance in the current-path region. This reduced impedance implies a low self-inductance and self-resistance that is caused by the current-path region. The low self-inductance provides an improved signal suppression over a broadened spectral range in a circuit configuration that employs the capacitor device as a bypass capacitor between a signal line and ground potential.
    • 描述了电容器装置,包括电容器装置的电子电路,电子部件和形成电容器装置的方法。 在电容器装置中,电流通路区域从两个沟槽电容器电极之一延伸到相应的接触结构。 通过在形成第一和第二接触结构之前,将衬底从原始衬底厚度减薄到包含电容器区域的横向衬底部分中或衬底的完全横向延伸部上以减小衬底厚度,从而获得电流通路区域。 电容器装置在电流路径区域中表现出减小的阻抗。 这种减小的阻抗意味着由电流路径区域引起的低自感和自电阻。 低自感能够在采用电容器器件作为信号线和地电位之间的旁路电容器的电路配置中的扩展光谱范围上提供改进的信号抑制。

    • The present invention relates to a capacitor device (500), an electronic circuit comprising a capacitor device, to an electronic component, and to a method of forming a capacitor device. In the capacitor device of the invention, a current-path region (530) extends from one of two trench capacitor electrodes to a respective contact structure (520). The current-path region of the capacitor device of the invention is obtainable by thinning the substrate from an original substrate thickness down to reduced substrate thickness either in a lateral substrate portion containing the capacitor region or over the complete lateral extension of the substrate before forming the first and second contact structures. The capacitor device of the invention has the advantage of exhibiting a reduced impedance in the current-path region. This reduced impedance implies a low self-inductance and self-resistance that is caused by the current-path region of the capacitor device. The low self-inductance provides an improved signal suppression over a broadened spectral range in a circuit configuration that employs the capacitor device of the invention as a bypass capacitor between a signal line and ground potential.

    • A coupler (10) having a first line (1) and a second line (2) also comprises a resonant structure (3) including a capacitor (5) and an inductor (4). The coupler (10) thus delivers a coupling signal S31 that is substantially frequency independent over a frequency domain above the resonance frequency of the resonant structure (3). Also, the signal S31 has a high degree of directivity. The coupler (10) can be provided as part of an integrated electronic component, such as a multilayer substrate, a thin-film module or an IC. It can be applied in an electronic device (100) between a power amplifier (101) and an antenna (103). The coupling signal S31 will thus be provided to a controlling circuit (102).
