Abstract: A bulk acoustic wave resonator has an adjustable resonance frequency. A piezoelectric element is provided having first and second electrodes. A switching element is provided in the form of a MEMS structure which is deformable between a first and second position. The switching element forms an additional electrode that is selectively disposed on top of, and in contact with, one of the first and second electrodes. This causes a total thickness of the electrode of the resonator to be changed resulting in a modification of the resonance frequency of the resonator.

Abstract: A built-in circuit includes a semiconductor substrate (SB) with a bottom part (PSB) and upper layer (CSB) strongly doped that the bottom part. A first block (BC3) and a second block (BC1) are formed in the upper part of the substrate. An isolating device is arranged closed to the second block (BC1) and includes an isolating circuit (CRS) linked to the bottom part of the substrate (PSB). A mass connection (PTMD1) provide a minimal impedance at a given frequency.

Abstract: Un dispositif de modulation de signaux comprend un modulateur sigma-delta (8) disposé pour transformer un signal de modulation d'amplitude en bande de base en un signal d'impulsions (C). Il comprend en outre un modulateur de phase (7) recevant en entrée des signaux analogiques de modulation de phase en bande de base (I, Q). Le signal d'impulsions (C) est mélangé à des signaux de porteuse (P1, P2) en amont du modulateur de phase (7). Le dispositif de modulation est adapté pour constituer un étage d'entrée d'un émetteur.

Abstract: The receiving circuit for bits transmitted on an asynchronous signal (Din) consists of a circuit which provides a reconstructed clock from an asynchronous signal. The clock is designed to sample the asynchronous signal to form a synchronised output signal (Ds). The receiver also has a reception error detection circuit. The error detection circuit consists of a front detector (21, 22, 24, 25), which provides a detection pulse (UP, DN) for each leading edge in a predetermined direction for the asynchronous signal. An alarm circuit (27, 28) generates an warning signal when a leading edge of a synchronous signal (Ds) survives outside a detection pulse (UP, DP).

Abstract: The module has a dielectric substrates (6) bearing conducting aerial layer and a substrate (8) bearing circuit units (30) e.g. inductance, capacitor, and a conductive shield layer (10). Thickness and nature of the substrate are selected by holding account of surface of a conductive layer and stock points, so that the layer (10) is coupled to the earth by a capacitor constituting a short-circuit for the radio frequencies. The conductive shield layer (10) being floating is laid out between the dielectric substrates.

Abstract: The invention concerns a circuit for generating phase-shifted signals comprising at least two adders (15, 16) each including at least two inputs for receiving identical two-state phase-shifted signals, each input of each adder (15, 16) being assigned a positive or negative single-unit coefficient so that it generates in output of said adders (15, 16) two identical phase-shifted signals.

Abstract: The invention concerns a transmission-reception head of a high frequency signal in the form of an integrated circuit comprising a transmission amplifier (23) and a reception amplifier (22). The transmission amplifier transmission terminals and the reception amplifier reception terminals are interconnected in a common transmission-reception terminal (20). The head comprises means for selecting one of the amplifiers and means for placing the other amplifier in a state of high impedance, relative to the transmission-reception terminal.
