A Wideband 360° Analog Phase Shifter Design
This paper proposes a reflection-type wideband 360 ° analogue phase shifter. The phase shifter employs a branchline coupler circuit to achieve a wideband operation and a varactor-diode circuit to achieve a wide phase-shift range. Analytical formulas are derived to optimize the parameters in the coupler circuit for wideband operation and reduced attenuation ripple, and in the varactor circuit to...
متن کاملDesign of a High - Resolution Microfluidic Microwave Mems Phase Shifter
In this article, a novel microwave microelectromechanical phase shifter based on a microfluidic design is proposed and demonstrated. The design principles, the fabrication process, and experimental results (S-parameters and phase shift plots) are presented. The proposed system has a high bandwidth, high-power handling capacity, and a high-resolution along with a small settling time. VC 2011 Wil...
متن کاملDesign of Mems Based Tristate Phase Shifter Using COMSOL 4.3b
A V-band CMOS-MEMS switchable phase shifter based on reflection-type topology is presented in this work. Phase shifter is simulated by using CMOS process. Three discrete phase states are achieved at 65GHz by using Bi-directional fishbone actuators. The measured insertion is very less and the return loss is also better than 14 dB over the 55-65GHz frequency range. It demonstrates a great potenti...
متن کاملA New Design of Dual Band Phase Shifter using MEMS Technology
Abstract - This paper presents a new design of microwave microelectromechanical systems (MEMS) phase shifter for dual band wireless local area network (WLAN) applications. A bit is designed which product a constant phase shift of 11.25° by switching between two line that consist of 12 and 6 unitcells in each frequency band. A unitcell is constructed by gold membrane suspended over the coplanar ...
متن کامل-uwb Phase Shifter
Aim of the project: The aim of the project is to design a 3-bit UWB Phase-shifter and implement one bit of it on a transmission line. Types of Phase Shifters: The Phase shifters can be grouped in two types. 1. Ferrite Phase Shifters 2. PIN diode phase shifters Ferrite Phase Shifters are activated by a pulsed current and power requirements are usually less than their PIN diode counterparts. Anot...
