The design, assembly and characterization of a
phase switch in the Ka-band based on PIN diodes is
presented. This phase switch has provided a 20 per cent
of bandwidth at 30 GHz and a phase shift around 180º.
The phase switch has been made with a broadband
hybrid coupler on microstrip technology and commercial
PIN diodes HPND-4005 from Agilent. Two different
techniques to adjust the phase shift have been applied.
Input and output matching better than 13 dB, return
losses lower than 3 dB and a phase shift from 160º up to
174º have been obtained from 27 to 33 GHz.
