Abstract

A design of a microwave phase shifter based on a loaded microstrip line using planar SrTiO3 capacitors as nonlinear elements is described. The microwave phase shifter (at T=300 K) demonstrated a continuous phase shift between 0 and ∼55 deg in the frequency range 8.6–9.0 GHz with a phase error not exceeding 5 deg. The quality parameter of the phase shifter in the operating frequency range was 110 deg/dB.
