摘要： The present invention relates to a method for producing an antenna operating in a given frequency band, from a dual-band antenna. According to the method, the dual-band antenna is a broadband slot antenna that receives and/or transmits electromagnetic signals at a first frequency and at a second higher frequency. The antenna is powered by a single power supply line, and the free end of the power supply line is connected, by a connection means that can be opened or closed, to at least one means for rejecting one of the frequencies. This invention can be used in producing generic electronic boards.

摘要： The invention provides a dielectric resonator oscillator DR, especially for transmission devices whose oscillating frequency may take several values. The oscillator uses two interfering conductors 30 and 31 switched so that they may or may not form a metal plane close to the dielectric resonator DR in order to vary the frequency of the oscillator while using a single resonator. The interfering conductors 30 and 31 are located in the cavity CAV close to the resonator DR and the switching means may or may not establish an electrical contact between the said interfering conductors 30 and 31.

摘要： The invention relates to a switch with selective isolation and also to a switching device with selective isolation for multimedia terminals. The switch formed by 2 transistors (T1, T2) is feedback controlled by a feedback control signal V tune at a pre-defined frequency thus guaranteeing the selective isolation at this frequency. The switching device for switching the transmission/receiver channels of a multimedia terminal is formed by selective isolation switches that can be integrated using MMIC technology.
