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 کاملWideband 180◦ Phase Shifter Using Microstrip-cpw-microstrip Transition
Abstract—A microstrip 180◦ phase shifter obtained by a novel design of Microstrip-to-Coplanar Waveguide (CPW)-to-Microstrip transition is presented. The proposed phase shifter is obtained without changing the layer of the second microstrip line. Via holes are used to transfer the current from the top to the bottom substrate layer and vice versa. The presented phase shifter is operating in a wid...
متن کاملA Wideband Current-mode, Low-Voltage, Low-Power CMOS Frequncy- insensitive Quadrature Phase Shifter
A CMOS frequency-insensitive quadrature phase shifter is presented. Due to operation in current-mode, the proposed circuit provides a wide frequency response, a low supply voltage, low power consumption and electronic controllability. Thus, it is very suitable for use in portable and battery-powered equipments. The feature of the proposed circuit is that it can provide the quadrature signals wi...
متن کاملA New Circular Polarization Metamaterial Ferrite Phase Shifter
In this paper, a new X band Metamaterial (MTM) based ferrite phase shifter is presented. The phase shifter is excited by circular polarized wave base on combination of TE10 and TE01 modes in a square waveguide. In order to synthesize negative refractive index metamaterial (NIM), negative permeability of ferrite slabs in extraordinary mode is mixed with the negative permitivity of printed period...
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...
