Abstract

A reflection-type coplanar waveguide (CPW) phase shifter fabricated using a standard monolithic microwave integrated circuit (MMIC) process is presented. Air-gap overlay CPW couplers were employed for wideband 3 dB coupling and low loss at millimetre wave. The two-stage cascade analogue phase shifter showed insertion losses of 6.9 ± 1.6 dB, return losses > 10 dB, and maximum rms phase error of ± 5.5° for the relative phase shift from -20° to 135°, over a wideband 27 to 47 GHz.
