Wideband low-phase shift digital step attenuators
Arash, Ebrahimi Jarihani; Koçer, Fatih; Department of Electrical and Electronics Engineering (2016)
Digital Step attenuators are used in many communication systems to regulate the signal level to achieve maximum system performance. The figure of merit of these attenuators are linearity, accuracy, and their power handling capabilities. Attenuators currently offered in the industry performs well to meet stringent requirements of the modern communications systems. However, all step attenuators currently offered introduces a phase-shift with respect to the attenuation setting and frequency. This phase-shift c...
Wideband phase shifter for 6-18 Ghz applications
Boyacıoğlu, Gökhan; Demir, Şimşek; Department of Electrical and Electronics Engineering (2010)
Phase shifters are common microwave circuit devices, which are widely used in telecommunication and radar applications, microwave measurement systems, and many other industrial applications. They are key circuits of T/R modules and are used to form the main beam of the electronically scanned phase array antennas. Wideband operating range is an important criterion for EW applications. Hence, wideband performance of the phase shifter is also important. In this study, four wideband phase shifter circuits are d...
Wideband phase shifter design using lange coupler and radial stubs
Boyacioǧlu, Gökhan; Demir, Şimşek (2010-12-20)
In this study, four wideband phase shifter circuits are designed and simulated for 6-18 GHz frequency range. Phase shifters are separately designed in order to get 11.25°, 22.5°, 45° and 90° phase shifts with minimum phase error and low return losses. Thin film production technique will be used to fabricate individual phase shifter circuits. Designs and EM simulations are performed by using Sonnet and ADS2008®. © 2010 IEEE.

Wideband Quarter Wave Transformer Based on Defected Ground and Split Ring Resonator Structures
Yuksek, Yahya; Nesimoglu, Tayfun (2018-11-02)
This article examines a wideband impedance transformer based on a split ring resonator and defected ground structures. The transformer was designed as a 4 section binomial one and it provides a transformation from 50 SI to 100 Omega. Reversed "Z" shaped defects are formed on the ground plane of the design in order to increase the bandwidth. The design has been simulated using a 3D electromagnetic simulator which utilizes finite integration technique. Three distinct resonances are exhibited at specific frequ...
