    • A circuit arrangement is described having a terminal (1) for a high-frequency signal, having at least two additional signal leads (21a, 21b, 21c, 22a, 22b), having a switching unit (3) for connecting the terminal (1) to a signal lead (21a, 21b, 21c, 22a, 22b), having a primary protection device (41) against electrostatic discharges, which is connected between the terminal (1) and the switching unit (3), the protection device (41) containing a first voltage limitation element (51), which diverts voltage pulses that exceed a switching voltage of 200 V to a reference potential (7). The use of a gallium arsenide double diode makes it possible to attain the advantage of a low insertion loss coupled with a low switching voltage.

    • A transmitter module of a wireless transmission system with at least one transmission path having a power amplifier disposed at the input side includes a low-pass filter disposed at the output side and an impedance converter disposed therebetween. The power amplifier and the low-pass filter are, thereby, disposed on the top surface of a multi-layer carrier substrate. Preferably, the impedance converter is disposed in metallization planes of the carrier substrate. The inventive integration of all of these components in one module especially allows for a step-wise impedance adaptation between the low-impedance amplifier output and the output of the transmitter module having a defined output impedance (e.g. 50 ohm), whereby the impedance adaptation is partially carried out by the low-pass filter. A multistage impedance adaptation allows for a reduction of, e.g., the length of the line sections used in the impedance converter and the signal losses involved.
    • 具有设置在输入侧的具有功率放大器的至少一个传输路径的无线传输系统的发射机模块包括设置在输出侧的低通滤波器和设置在其间的阻抗转换器。 因此,功率放大器和低通滤波器设置在多层载体衬底的顶表面上。 优选地,阻抗转换器设置在载体衬底的金属化平面中。 本发明将所有这些组件集成在一个模块中特别允许低阻抗放大器输出与具有确定的输出阻抗(例如50欧姆)的发射机模块的输出之间的逐步阻抗适配,由此阻抗适配 部分由低通滤波器进行。 多级阻抗适配允许减少例如在阻抗转换器中使用的线路段的长度和所涉及的信号损耗。
