Abstract :
Design method, fabrication process and measurement results of a linear analogue phase modulator in Ka-band with abrupt varactor diode are presented. The modulator was realised in integrating waveguide technology, which is based on a completely dielectric-filled rectangular waveguide. The 180° phase shift over the frequency band 34.3¿35.4 GHz has been received with phase nonlinearity less than 3.5% and insertion loss of 3 ± 0.4 dB.
