Experimental Investigation on the Effect of Central Wavelength Tuning of FBG-Based Phase Shifter for Raman-Assisted Phase Sensitive Amplifier
A FBG-based pump-phase-shifter is used in the Raman-assisted PSA. By actively tuning the FBG central-wavelength to enable pump phase optimization, up-to-5.6dB signal gain is observed. An improvement of ~6% EVM and ~4dB system sensitivity is observed by 20/25-Gbaud QPSK signals. Introduction Capacity upgrade utilizing higher level modulation formats such as 64QAM and 256QAM has been studied aggr...
متن کاملCurrent Mode First Order Phase Shifter Based on CDTA
This paper presents simple current controlled current mode first order phase shifter based on a modern active building block for analog signal processing, namely current differencing transconductance amplifier (CDTA). The proposed phase shifter consists of only single CDTA and one grounded capacitor. Any lump resistor component is not required thus it is possible to suit for IC implementation. ...
متن کاملPhase shifter based on DDS-driven offset-PLL
Introduction: Phased antenna arrays are very popular owing to their performance. Many passive techniques have been proposed, such as switched and loaded lines, in order to control the phase shift between array element feeders. These techniques are usually functional up to a few gigahertz, but it is very difficult to extend their use at higher frequencies owing to the critical tolerance in PCB p...
متن کاملTunable millimeter-wave phase shifter based on dielectric elastomer actuation
A very low-loss tunable millimeter-wave phase shifter driven by dielectric elastomer actuators (DEAs) is presented. The device consists of a fixed coplanar waveguide (CPW) and two metallic loading strips suspended on an elastomer membrane. The horizontal offset between the CPW and the strips is dynamically controlled by integrated DEAs. The variable interaction between the CPW and the loading s...

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...
