Abstract:

© 2018 IEEE. A wideband tunable phase shifter that uses the concept of reflection-type phase shifter is proposed. The device is based on a tunable high-directivity directional coupler. The coupler uses two pairs of interconnected coupled-lines with suitable coplanar-waveguide transmission lines embedded within the ground plane. The tuning is realized by using two varactors and two inductors connected to two terminals of the coupler. Full-wave simulation is performed using co-simulation within ADS momentum using accurate SPICE model of the tuning elements. Moreover, a prototype is fabricated and tested. The tested results reveal that the proposed design can achieve wide operating bandwidth (105% fractional bandwidth) with 40° tuning phase.
