Monolithic GaAs Phase Shifter Circuit with Low Insertion Loss and Continuous 0–360 Phase Shift at 20 GHz
نویسندگان
چکیده
We present here a circuit capable of continuous 0–360 phase shift at 20 GHz with only 4.2 dB of insertion loss. The phase shifter employs a variable velocity transmission line obtained by periodically loading a coplanar waveguide (CPW) line with GaAs Schottky diodes. The circuit is fabricated on GaAs using monolithic fabrication techniques that are compatible with commercial GaAs foundry processes. To the best of our knowledge, this circuit has the lowest reported insertion loss for a monolithic solid state phase shifter operating at 20 GHz.

Distributed Analog Phase Shifters with Low Insertion Loss
This paper describes the design and fabrication of distributed analog phase-shifter circuits. The phase shifters consist of coplanar-waveguide (CPW) lines that are periodically loaded with varactor diodes. The circuits are fabricated on GaAs using standard monolithic processing techniques. The phase velocity on these varactor diode-loaded CPW lines is a function of applied reverse bias, thus re...

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...

A 360" analog CPW MMIC phase shifter is presented for the first time. The compact MMIC employs eight multilayer 3 dB quadrature couplers and was fabricated using low cost GaAs foundry processing techniques. The phase shifter was required to implement a narrow band serrodyne frequency translator at 24 GHz. With an arbitrary, small-shift, frequency translation of +5 KHz, the measured results demo...
