Abstract: A connection assembly is provided. The connection assembly includes a socket with connection pins, a plug with matching connection pins and a locker for locking the plug relative to the socket while the matching pins are engaged. The lock includes a bolt having a barrel provided with balls movable between a locking position projecting in relation to the barrel and a position retracted inside the barrel, and a rod for retaining the balls in the locking position. The locker also includes a shaft arranged in the plug or the socket for at least partially receiving the bolt and having a groove for receiving the balls in the locked and projecting position. The bolt further includes a spring for returning the rod toward the ball-retaining position, and the rod has a cam surface pushing the balls back into the locked position when the spring urges the rod towards the retaining position.

Abstract: The present invention provides an antenna interface. The antenna interface includes a socket and a plug. The socket includes a body and two coaxial cables, each having a core, a braid coaxial to the core, and an electric insulator between the core and the braid. Each coaxial cable extends between a first end connected to a printed circuit board of the receiver and a second end at which the braid is electrically connected to the body, and at which the core can be accessed through an opening made in the body. The plug includes a body and at least two contactors such that, when the plug and the socket are connected, each contactor is arranged opposite an opening such that the core of a respective cable is electrically connected to the contactor, and the braid of each cable is electrically connected to the body of the plug via the body.

Abstract: A variable attenuation device intended to be inserted between a transmitter circuit having a certain internal impedance and a load circuit; it composed of at least on parallel attenuation branch made up from a variable resistance component (in particular a p-i-n diode) and a bias circuit to vary the resistance of the component as a function of an attenuation control variable. The parallel attenuation branch has a limiting component which is connected in series with the variable resistance component and whose value ensures the matching of the internal impedance of the transmitter circuit.
