Patent Number Title Of Patent Date Issued
8565695 Detection of the value of an impedance of a radiofrequency system October 22, 2013
A method and a device for determining the amplitude and the phase of an impedance connected on a transmission line, including a bidirectional coupler having a first line interposed on the transmission line and having a second line providing at its respective ends two measurement sign
7760155 Integrated coupler July 20, 2010
A non-directional coupler including a semiconductor junction in series with a capacitor, the semiconductor junction being formed so that the threshold frequency short of which it behaves as a rectifier is smaller than the coupler's operating frequency.
7671698 Wide-band directional coupler March 2, 2010
A directional coupler having a first structure with distributed lines having a first conductive line intended to convey a main signal between two end terminals and having a second conductive line, coupled to the first one, intended to convey a secondary signal proportional to the main
7623006 Power combiner/splitter November 24, 2009
A distributed combiner/splitter having a first line formed of a first planar winding in a first conductive level and of a second planar winding in a second conductive level, and a second line formed of a third planar winding interdigited with the first winding in the first level, and of
7589602 Antenna switch module September 15, 2009
An antenna switch module between several radio-frequency transmit and/or receive paths including, between a common terminal on the antenna side and an access capacitor specific to each path, at least one diode, the number of diodes directly connected to the common terminal being odd and
7459989 Integrated phase shifter of differential signals in quadrature December 2, 2008
A distributed phase shifter including: a first planar winding having its ends defining accesses in phase opposition; a second planar winding coupled with the first one and grounded by a first capacitive element; a third planar winding in a conductive level different from that receiving
7394333 Directional coupler July 1, 2008
A coupler of distributed type including a first conductive line carrying a main signal between two end terminals, a second conductive line coupled to the first one and between two terminals of which flows a sampled signal, proportional to the main signal, and two capacitors respectively
7375603 Integrated coupler May 20, 2008
A non-directional coupler including a semiconductor junction in series with a capacitor, the semiconductor junction being formed so that the threshold frequency short of which it behaves as a rectifier is smaller than the coupler's operating frequency.
