The network comprises a first ground line connected by its ends to first and second ground points connected directly to the ground plane, a second ground line connected via its ends to third and fourth ground points directly connected to the ground plane, a plurality of L/C resonant elements connected in parallel and linked via one end to one of the two ground lines and via the other end between them, by means of coupling inductors which thus create transmission zeros. Each ground line forming inductive elements via inductances the network comprises capacitive elements in series with at least some of said inductive elements, the value of the capacitive elements being selected so that the resonant frequency of the inductive and capacitive elements in series corresponds to a frequency lying outside of the bandwidth.

摘要： The invention relates to a selective active low-pass filter and to a method for improving the selectivity of such a filter. The method includes centering, in the center of a network, the resonant element whose frequency is closest to the cutoff frequency of the filter and in inserting in series with this element a negative resistance of higher value than the parasitic resistance of the filter.

摘要： The invention relates to a dual-response stopband filter as well as to a filtering device comprising such a filter. The dual-response stopband filter comprises between the input terminal and the filter output a first direct channel and a second channel, known as a secondary channel, coupled with the first channel and forming a resonant element. The filter further comprises, integrated on the first direct channel, a selective low-pass filter to reject a first selected frequency band and, integrated on the second channel a variable capacitor to form the stopband filter of a second frequency band that can be determined. The switching device is associated with the first channel to switch the low-pass filter and the second channel to switch the stopband filter.

摘要： The channel filter includes at a least one basic bandpass filter centred on the frequency of the channel, in series with two cascade-connected reflective filters whose bandwidths are located either side of the basic bandpass filter encompassing the channels adjacent to the channel. A reflective filter can include a 90° directional coupler combined with a bandpass filter designed to ensure transfer matched to the load impedance of the coupler with the input of the bandpass filter connected to a directional coupler output port, the input of the directive filter being formed by input port of the coupler and the output of the directive filter being formed by a port recovering the bandpass filter reflection coefficient. The invention applies in particular to the implementation of the DVB-T and DVB-H standards aimed at receiving digital television programs from fixed or mobile multistandard terminals such as mobile telephones, PDAs or other multimedia receivers.
