Abstract: In the field of satellite communication systems, a method is provided for managing communication resources allocated by central control equipment to the various terminal communication devices within a global satellite communication system. In particular, the management of communication resources by way of the monitoring of the equivalent isotropically radiated power transmitted by a terminal of the satellite communication system is provided.

Abstract: The present invention relates to a bidirectional frequency mixer, as well as a radiofrequency transceiver system including at least such a mixer. The mixer includes two ports separated in intermediate frequency FI, one for the reception, the other for the emission and a common port in frequency RF both for reception and for emission. It also includes at least fours mixing cells and three phase shifting means of signals used to remove the undesirable frequencies generated by the mixing cells. The mixer enables a rejection of the frequencies produced by a local oscillator in transmitting phase and a rejection of the image phase in receiving phase to be preformed. The invention is in particular applicable to designing microwave integrated circuits, in particular in millimetric frequency band.
