Popis: | Two differential phase shifters are designed and tested to work in broadband applications exhibiting excellent features. A phase delay of 90º or 180º with respect to a waveguide with the same length is obtained by including several steps inside the waveguides. The relative bandwidth of both phase shifters is about 40%. Two versions of 90° and 180° have been designed in the Ku-band. The return losses were about 25dB and the phase were about ±2° and ±3° for 90° and 180° phase shifter respectively. Moreover, a manufacturing tolerance has been taken into account at the design, and therefore, the designed phase shifters need not be tuned after manufacture. |
