    摘要: A method and apparatus for overmolding a plastic shroud onto a bobbin including the step of providing a protrusion ring on the surface of the bobbin surrounding each standoff between the bobbin and a mold wall and extending outwards from the surface of the bobbin. A plurality of standoffs and protrusion rings is presently preferred. The protrusion rings are small relative to the standoffs, have low thermal mass, and thus are readily melted by the injected molten plastic, causing interstitching between the bobbin material and the overmolding material. The interstitching creates a highly effective hermetic seal against moisture leakage along the surface of the bobbin away from the standoff site. Perfect melting of the standoffs is no longer required, and standoffs can be designed to assure proper positioning of the bobbin during the complete overmolding process.

    摘要: Modulation device for an RF power amplifier. A correction of the modulation pulse is defined from the non-linear control characteristic of the RF power amplifier (2) such that the influence on the desired output pulse shape caused by the non-linear control characteristic is first compensated for without involvement of a controller. When, due to disturbances acting on the amplifier, changes of the control characteristics or of the RF gain and, consequently deviations in the pulse shape and power occur, then the controller corrects these deviations during the pulse transmission. The modulation device is used in RF transistor power amplifiers having a pulse modulation input.

    摘要: An intermediate repeater or a regenerative repeater has a circuit arrangement for the coarse protection against surge voltages, the arrangement comprising current supply separating filters for the remote feeding via a remote feed current path, fed via the inner conductor of a coaxial cable, which contain a low-pass filter, respectively. In the case of a circuit arrangement of this type, noise pulses, which a surge voltage arrester causes, are to be greatly reduced with respect to edge steepness. To this end, a series connection is provided containing the surge voltage arrester and an inductance, which series circuit, via a low-pass filter disposed outside of the remote feed current path, is connected between the low-pass filters of the current supply separating filters to the remote feed current path and to a connection of the outer conductors of the cables.
