| 摘要 |
<p>The invention concerns DC-polarization devices for radio-frequency transmission systems of high power and low intermodulation, comprising a station (A) originating the RF signal, a station (B) receiving said RF signal from A, and a source D of direct current DC to be fed to B, and connected in a knot N to the line AB, the branches AN and DN comprising a short circuit stub (STU2) respectively an open circuit stub (STU1). Typically the normalised impedance (Z'op) of stub (STU2) is substantially equal to the normalise admittance (Yos) of stub (STU1), and the distance of the free heads of the near ends of the two stubs is the lowest possible. <IMAGE></p> |
