| 20100134700 | CHANNEL FILTER, IN PARTICULAR FOR A DIGITAL TELEVISION RECEIVER - 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 programmes from fixed or mobile multistandard terminals such as mobile telephones, PDAs or other multimedia receivers. | 06-03-2010 |
| 20110050363 | ACTIVE LOW PASS FILTER - The invention relates to a selective active low-pass filter and to a method for improving the selectivity of such a filter. The method consists in centring, in the centre of the network, the resonant element whose frequency is closest to the cut-off 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. | 03-03-2011 |
| 20110090125 | FRONT END BLOCK WITH INTERGRATED ANTENNA - The invention relates to an RF reception front end block comprising a first substrate and an RF integrated front end module integrated onto a second substrate supporting a radiating part of the antenna. | 04-21-2011 |
| 20110158136 | DUAL-MODE MIXER - The present invention relates to a mixer for signals at different frequencies comprising a network of diodes formed by a pair of diodes mounted in an anti-parallel manner, the first linking point of the diodes being connected to the ground, the second linking point being connected to the ports of transmission/reception signal paths and to the port of a local oscillator path at different frequencies. An impedance matching network for dual-mode use is connected in series in the diode network between the first linking point connected to the ground and the anode of one of the diodes of the diode network. A filtering network is connected between the second linking point and each of the ports of the transmission/reception paths and of the local oscillator path. | 06-30-2011 |
