Design of Broadband Impedance Matching Circuit for PLC Coupler using Butterworth Equalizer

بهینه سازی و افزایش پهنای باند پیوننده خط شاخه ای موجبری مجتمع شده در زیرلایه به روش حداقل مربعات

Directional couplers are passive devices which are used as power dividers and combiners in microwave, millimeter and terahertz systems. By the use of substrate integrated waveguides (SIW) for the design of such devices, the advantages of waveguide and printed circuit (PC) technologies are utilized simultaneously, such as low cost, small size, low transmission and radiation losses. In this paper...

A Broadband Low Power CMOS LNA for 3.1–10.6 GHz UWB Receivers

A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...

Broadband MIMO Couplers Characterization and Comparison

THIS paper focuses on MIMO Power Line Communication (PLC) to provide increased performance. In MIMO PLC, appropriate coupling methods are necessary in order to enable the effective injection of the signal through the broad band PLC channel so that high data rates can be achieved [1], [2], [3]. In the literature, different kind of couplers are proposed [4],[5]. In this paper, we want to characte...

Broadband Amplifier Gain Slope Equalization Filter

Since the achievable gain of transistors typically falls off as the frequency increases, an equalization filter with positive gain slope is necessary to compensate for the gain roll-off of broadband amplifiers. This paper proposed an novel equalizer structure and design a equalization filter by applying this novel structure and a modified SIW-PBG (Substrate Intergrated Waveguide-Photon BandGap)...
