    摘要: This invention concerns a repeater for radio frequency signals.The repeater at least includes: a channel filter; an active filter connected to the channel filter output, covering the channels adjacent to the channel filter comprising: an amplifier the output of which forms the output of the said filter; two bandpass filters in parallel connected as a negative feedback loop around the amplifier, with a first bandpass filter covering the lower adjacent channels and a second bandpass filter covering the higher adjacent channels. The repeater can also include: a circuit converting the radio frequency signal into an intermediate frequency, with the channel filter filtering the signal converted into an intermediate frequency; a circuit converting the signal into an intermediate frequency at its original frequency. The invention notably applies to the development of domestic repeaters for mobile terminals meeting the DVB-H digital television standard.

    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.
