CONTROLLED CORRECTION TILT frequency response tract microwave

摘要

The invention relates to the field of radio engineering and may be used to equalize the amplitude-frequency characteristic (AFC) microwave paths. The technical result of the proposed utility model is to extend the operating bandwidth and reducing the quadratic component of the frequency response distortion by introducing depth adjustment elements amplitude correction. Proposed controllable gain slope equalizer comprising a quadrature directional coupler (CCW) on the associated lines to the diagonal shoulder which included the same reflecting cell with a frequency-dependent reflection coefficients, which is selected so that the reflectance was a maximum in the frequency of the working range where required a maximum transmission rate and controllable attenuators (e.g., pin diode microwave transistor chip attenuator microwave) included between each diagonal shoulder CCW and the reflecting unit. The frequency dependence of the transmission coefficient of the reflecting cells is determined in each case, for example, can be applied microstrip line segment. The introduction of two controllable attenuator allows you to change the amount of communication with the CCW reflective cell and, accordingly, to adjust the frequency response correction of the depth adjustment without reflecting on the frequency of the cell.
