摘要：

A distributed transmission line phase shifter based on two series connected parallel-plate ferroelectric thin film varactors, which are integrated into single crystal (1 0 0) LaAlO3 (LAO) wafer, is presented. The equivalent circuit model was simulated by the EM simulation software in an effort to optimize the design. A device with differential phase shifts of 150 degrees at 8 GHz with a low bias voltage of 12 V was realized. (C) 2009 Elsevier B.V. All rights reserved.
