摘要： The present invention relates to a FINLINE type microwave band-pass filter comprising a waveguide provided with an insulating substrate placed in an E plane of the guide and comprising on at least one of the surfaces, conductive inserts electrically connected to the internal surfaces of the guide which support the substrate and which determine by their dimensions and their positioning on the substrate a Chebyshev type filter response curve. The filter includes at least one cavity in perpendicular short circuit to the substrate, the positioning and the dimensions of the cavity determining a transmission zero on the filter response curve for attenuating the frequencies situated around this zero. Such a filter is used in particular in transmission terminals operating in the Ka band.

摘要： The invention relates to processes and devices which make it possible to directly modulate an RF carrier with a quadrature signal. It consists in filtering (504) this quadrature signal around zero so as to introduce alternately (507, 508) on each of the channels a low-frequency subcarrier that will serve as reference. Each of these channels is alternately demodulated in a synchronous manner (519) cosine-wise and sine-wise. The demodulation signal is filtered (523) so as to recover the subcarrier marred by modulation errors. The measurement of these errors (524) allows feedback correction (503) of the quadrature signal. It makes it possible to perform the major part of the operations in the digital processor (501) and enables direct vector modulation to be made possible at millimeter frequencies.
