Broadband Impedance Transformation by Defected Dielectric on Microstrip Lines
Kaya, Tevfik; Nesimoglu, Tayfun (2018-11-02)
In this work, a different approach to achieve a desired characteristic impedance value on microstrips is presented. In standard microwave circuits using microstrip lines, the dielectric thickness is same and uniform across the whole circuit. In this paper, it is proposed to modify the dielectric thickness to achieve a certain design goal by creating variations in the characteristic impedance of the microstrip transmission line without changing the width of the line. The proposed approach is applied to a mul...

BROADBAND HIGH EFFICIENCY RF POWER AMPLIFIER DESIGN BASED ON MODIFIED CLASS-J APPROACH WITH APPLICATIONS USING GAN HEMT TECHNOLOGY
Koç, Murat; Demir, Şimşek; Department of Electrical and Electronics Engineering (2021-9-29)
RF power amplifiers have been the essential elements of any transmit/receive block. Especially in the transmit chain, some applications require high RF power, such as radar, jammer, telecommunication signals targeting a wide range of coverage. High power requirements in RF broadcast mean high supply power to feed RF PA. The efficiency parameter of a high-power transmission system becomes an issue due to heating problems and performance degradation depending on rising temperatures. The heating problem is com...
Broadband One Way Propagation via Dielectric Waveguides with Unequal Effective Index
Oner, B. B.; Ustun, K.; KURT, HAMZA; OKYAY, Ali Kemal; Sayan, Gönül (2014-10-16)
We present an efficient approach for broad band one way propagation of light by parallel and unequal dielectric waveguides leading different effective phase shifts. Three dimensional numerical simulations show that 30% operating bandwidth is achieved.
Broadband THz Modulators Based on Multilayer Graphene on PVC
KAYA, Emine; Kakenov, Nurbek; Kocabas, Coskun; Altan, Hakan; Esentürk, Okan (2016-09-30)
In this study we present the direct terahertz timedomain spectroscopic measurement of CVD-grown multilayer graphene (MLG) on PVC substrate with an electrically tunable Fermi level. In a configuration consisting MLG and injected organic dopant, the transmitted intensity loss of terahertz radiation was observed with an applied voltage between 0 and 3.5 V.We showed that MLG on PVC devices provided approximately 100 % modulation between 0.2 and 1.5 THz at preferentially low operation voltage of ca. 3V. The obse...
