Microwave equaliser with internal amplitude correction

摘要

Microwave equaliser with internal amplitude correction, preferably for application in satellite communications, comprising at least one resonant cavity (2), at least one incoming signal injection means (6) that projects into said resonant cavity (2) for injecting signal into said resonant cavity (2), and at least a first resistive tuning means (5). The position of said first tuning means (5) with respect to said input signal injection means (6) produces electromagnetic coupling between both means (5) and (6), giving rise to an amplitude attenuation effect in said signal. A variation in said relative position between said means permits changing said attenuation in a selective manner. A second resistive tuning means (7) can be used in combination with the first resistive tuning means (5) to optimise the response of the equaliser. <IMAGE>
