    摘要： A radio frequency (RF) device includes electronic circuitry having a radio frequency section and power connectors for electrically connecting the electronic circuitry to at least one power source for providing the device with power. At least one quarter wavelength transmission line is connected between the power connectors and the electronic circuitry and acts as a low-to-high impedance transformer at RF, while at low frequencies i.e. DC, it provides a physical connection. Thus, the transmission line section has substantially no effect on the DC connection between the power source and the device.

    摘要翻译： 射频（RF）设备包括具有射频部分的电子电路和用于将电子电路电连接至至少一个电源的电源连接器，用于向设备提供电力。 至少四分之一波长传输线连接在电源连接器和电子电路之间，并且在RF处作为低至高阻抗变压器，而在低频率（即DC）时，它提供物理连接。 因此，传输线部分对电源和设备之间的直流连接基本上没有影响。
