20100079958 | TRANSISTOR CLAMPING DEVICE - A transistor-clamping device for a transistor is provided with a holding block and a spring. The holding block engages over the transistor, so that the spring is pre-tensioned. A pressure plate is provided between the holding block and the transistor. The spring fixes the pressure plate on the transistor, so that a uniform pressure is applied to the transistor via the pressure plate, and, at the side facing away from the pressure plate, the latter accordingly provides a good thermal conduction to a cooling element. | 04-01-2010 |
20120280750 | CIRCUIT ARRANGEMENT FOR A REDUNDANT POWER SUPPLY FOR A POWER AMPLIFIER - The switching arrangement is used for the redundant power supply for a power amplifier, especially a high-frequency power amplifier. The power amplifier in this context provides several output-stage components and several power-supply units. The power-supply units are connected together at their load-end connections and supply the output-stage components jointly with energy. If a power-supply unit fails, at least two output-stage components are actively switched off, so that the power amplifier can continue to operate although with reduced output power. | 11-08-2012 |

20080231388 | Broadband Balancing Transformer - A balance-to-unbalance transformer (balun) comprising a first signal input/output with two symmetrical poles, a second signal input with one pole, several first conductor loop regions, which are located between the two poles of the first signal input and the ground and a second series connection of several conductor loop regions, the first terminal of the latter being connected to the pole of the second signal input. Two second conductor loop regions are electromagnetically coupled to a respective conductor loop region. The second outer terminal of the second series connection of several second conductor loop regions is electrically connected to the intermediate terminal of a first series connection of several first conductor loop regions, which connect a symmetrical pole of the first signal input to the ground. | 09-25-2008 |
