摘要： A radiofrequency circuit embedded onboard a satellite, data being transmitted on several channels by radiofrequency signals, includes a channel corresponding to a frequency band, and a succession of gains being able to be associated with a channel so as to generate the radiofrequency signal to be transmitted on the latter. The succession includes at least one variable-gain amplifier, the radiofrequency signals thus generated being multiplexed by a multiplexer composed of bandpass filters. The successions of gains comprise a power load arranged so as to dissipate the power of signals which is reflected by the filters of the multiplexer, said load including means for generating an alarm signal representative of the power level of the reflected signals, the alarm signal being used to control the gain of the variable-gain amplifier. The subject of the invention is also a power load.

摘要： A filter of longitudinal axis Z includes: at least one resonant cavity delimited by walls made of a material that has a non-zero expansion coefficient; a dielectric resonator mounted in the cavity transversally to the axis Z; a mechanical device for compensating at least one resonance frequency of the cavity as a function of the temperature. The compensation device comprises: at least one rotationally mobile finger for each mode and for each cavity, the mobile finger penetrating to a fixed depth into the cavity via a pivot link, and an external mechanical actuator mounted parallel to the axis Z and mechanically coupled to the mobile finger, the external mechanical actuator being made of a material that has a coefficient of thermal expansion at least five times lower than that of the walls of the filter.

摘要： A resonant cavity device comprises a waveguide body having a lateral wall extending in a longitudinal direction, having a first coefficient of thermal expansion, and delimiting a resonant cavity in conjunction with opposite first and second end walls. The first end wall has a second coefficient of thermal expansion lower than the first coefficient and has an internal face fastened to a first assembly comprising at least one main plate having a third coefficient of thermal expansion lower than the first coefficient and dimensions in a plane perpendicular to the longitudinal direction less than but substantially equal to those of the cavity. An intermediate member has a fourth coefficient of thermal expansion lower than the third coefficient and an end portion fixed to the main plate which, in the event of a temperature variation, converts a dimensional variation in a direction perpendicular to the longitudinal direction into a dimensional variation in the longitudinal direction inducing longitudinal translation of the main plate inside the cavity.
