摘要： 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).

摘要： A method for producing a heterobipolar transistor, arranged on a substrate of semiconductor material on which is grown a semiconductor sequence for a collector, a base and an emitter, which method includes: etching the layer sequence to form a transistor with a mesa structure, carrying out a first planarizing step to the upper limit of the base during which the surface of the base is protected by a protecting portion of the emitter layer adjacent to the base; removing this protective layer; depositing a metal contact layer for the base; carrying out a second planarizing step for the base emitter mesa; and finally depositing a connecting metallization layer for the collector, base and emitter.
