Very Small Size ka Band 6 Bit DMTL Phase Shifter Based on Combination of Capacitor and Resonator Type Methods
Abstract- Design and simulation of a very small size 6-bit DMTL phase shifter is presented. The idea is based on using both capacitor and resonator type methods simultaneously in a phase shifter. The capacitor section creates less significant bits. The bits in this section start from the least significant bit, with 5.625-degree steps. The resonator section creates the bits with 90-degree steps....
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...
متن کاملPhased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
متن کاملPhase shifter calibration in phase-shifting interferometry.
This paper describes some practical methods to calibrate the phase shifter in phase-shifting interferometry (PSI). The phase shifter used in the experiment is a piezoelectric transducer (PZT) that has a nonlinearity of <l%. Using the quantitative method described in this paper, the repeatability in the measurement of the phase-shifting angle is ̃9.046 rms, and the 3σ value is 0.139. A calibratio...
متن کاملMultichannel vector sum phase shifter.
A novel multichannel vector sum phase shifter that is suitable for phased array antenna applications is demonstrated. Each channel is implemented using a distinct optical wavelength. Selective control of each channel is performed using an acousto-optic polarization coupler. The concept is successfully demonstrated for two individually controlled channels. For each channel, a continuously variab...
