    摘要： An antenna is orientable, directional and capable of use as a transmit and/or receive antenna. It includes at least one reflector, at least one source of electromagnetic radiation including means for exciting the source with two orthogonal linear polarizations and a mechanical system for positioning and holding the source and the reflector. The orientation of the antenna is made up of depointing and rotation about a preferred direction of propagation of the radiation and the mechanical system enables such rotation while keeping the source fixed, so conserving the orientation of the orthogonal linear polarization. A preferred embodiment of the antenna includes a parabolic main reflector and a hyperbolic auxiliary reflector in a Cassegrain geometry, and the mechanical system enables rotation of both reflectors about the preferred direction of radiation and holds the source fixed to conserve the orthogonal linear polarization axes of the beam. Applications include radar, direct broadcast satellites and telecommunications employing frequency re-use by polarization diversity, especially advantageous in space and airborne applications.

    摘要： A time-continuous tunable Gm-C integrator including a "super Gm" differential input stage (O1; MI1/O2, MI2) and using linear and constant degeneration resistors (R1/R2) for obtaining the most optimal linear input-voltage to output-current conversion is tunable in a time-continuous manner. The integrator is provided with three tuning CMOS transistors (MU1, MU2, MU3) controlling the integrating currents flowing between the input stages and from the input stages towards the outputs (OP/ON). By a suitable control of the tuning transistors and owing to the fact that the voltage swing across the latter is small, it is possible to obtain a perfectly linear transconductance (Gm) characteristic over the whole operating range of the integrator.
