    • An electrical circuit includes an antenna connection for receiving a signal, a first signal path connected to the antenna connection, a filter arranged in the first signal path, and a first and a second gate circuit connected in series. The first gate circuit is connected to the antenna connection, and the second gate circuit is arranged between the first gate circuit and the filter. The first and second gate circuits each includes an impedance transformer arranged in the first signal path and a shunt circuit connected to ground. The shunt circuit includes a switch element and a capacitor. When the switch element is enabled, the shunt circuit defines a ground path through which at least part of the signal can pass to ground.
    • 电路包括用于接收信号的天线连接,连接到天线连接的第一信号路径,布置在第一信号路径中的滤波器,以及串联连接的第一和第二门电路。 第一门电路连接到天线连接,第二门电路设置在第一门电路和滤波器之间。 第一和第二门电路各自包括布置在第一信号路径中的阻抗变换器和连接到地的分流电路。 分路电路包括开关元件和电容器。 当开关元件使能时,分流电路定义了接地路径,至少部分信号可以通过该通路传递到地。
