  • Patent number: 8971056
    Abstract: A hermetically sealed HF front end (e.g. a transmission/reception module) in a multilayer structure that includes electronic components is provided. The multilayer structure contains a plurality of substrates stacked one above the other and carrying the components. Grooves are formed in the substrates and sealing elements are provided between the substrates, which sealing elements engage in the grooves, and the substrates are soldered together.
    Type: Grant
    Filed: September 18, 2010
    Date of Patent: March 3, 2015

  • Patent number: 6876323
    Abstract: A radar system with a phase controlled antenna array that contains a number of data and supply networks (2), which are installed so that they are interchangeable, and a transmit/receive module (3) containing a transmitter and receiver circuit (4) as well as a number of circulator circuits (8) and a number of antenna elements (9) that are coupled via a circulator circuit (8) to the transmitter and receiver circuit (4). Transmitter and receiver circuits (4), circulator circuits (8), and antenna elements (9) are combined in each transmit/receive module (3) and the transmit/receive modules (3) are arranged interchangeably on the radiation side of the radar or EW system (1).

  • Patent number: 5659265
    Abstract: A driver circuit for the generation of a switching voltage, particularly a negative switching voltage, which is suitable for GaAs technology. Field effect transistors whose electric properties can vary within a wide range and ohmic resistances that do not have to be adjusted later are used. The driver circuit is particularly suited for the selection of HF components.

  • Patent number: 5488328
    Abstract: A constant-current source that contains two substantial identical field effect transistors as well as a simple resistance network. The actual saturation current of one of the field effect transistors is measured and converted by the resistance network into a control voltage for the other field effect transistor which produces the desired constant current. With such a circuit, production tolerances, especially tolerances for field effect transistor, as well as operation-dependent temperature variations can be compensated for within a wide range.

  • Patent number: 5446464
    Abstract: A high frequency transceiver includes a transmit/receive switch which is coupled to a transmission path and to a receive path of the module. The transmit/receive switch includes a 3 dB directional coupler having first, second and third ports, and a decoupled port which is connected to the receive path. Two HF power amplifiers are connected to the first and second ports of the transmit/receive switch to form a balanced amplifier in the transmission path. An HF switch is connected to the first and second ports of the transmit receive switch for short-circuiting the HF output of the balanced amplifier. A switching device is connected to the HF switch and to the receive path for selectively switching the transmission path and the receive path to be operational.
