چکیده

This letter presents miniaturized Gysel power dividers using lumped-element components. The characteristic impedances of all the equivalent transmission lines in these dividers are fixed to the same values based on even and odd mode analysis, thus simplifying the design procedure and miniaturizing the Gysel power dividers. The ideal divider designed at a frequency of 590MHz exhibits power splits of −3.2 ± 0.2 dB and return losses of greater than 15 dB for the frequency range of 460 to 650MHz. Furthermore, isolation between output ports is greater than 15 dB for the frequency range of 500 to 680MHz. The fabricated miniaturized Gysel power divider achieves broadband characteristics and is very compact, occupying only about 15% of the area of a conventional Gysel power divider.

Design of a Two Octave Gysel Power-Divider Using DGS and DMS

This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five resistors is selected and optimized based on Quasi Newton method. Then the Defected Microstrip Structure (DMS) and Defected Ground Structure (DGS) is used to obtain better tra...

High Frequency Design 90 - DEGREE COUPLERS Classic Designs for Lumped Element and Transmission Line 90 - Degree Couplers

C ouplers (or power divider/combiners) with outputs that differ in phase by 90 degrees are an important part of RF/microwave design. This tutorial provides an overview of various types of 90-degree combiners, using both lumped element and transmission line structures. Our intention is to introduce the subject to engineers who may be unfamiliar with these couplers, and perhaps offer some reminde...

Compact Wideband Gysel Power Divider with Arbitrary Power Division Based on Patch Type Structure

A novel Gysel power divider based on patch type structure is presented in this paper. The proposed power divider possesses broad bandwidth, small physical occupation and arbitrary power division. More than 30% bandwidth enhancement is achieved based on the −15 dB input return loss criteria, while 55% size reduction is realized compared with conventional Gysel power divider. What’s more, flat di...

Lumped Element 180 Wilkinson Dividers and a Rat-Race Divider

-A lumped element 180 Wilkinson divider consisting of 11 elements was presented in 2003. It used a conventional Wilkinson divider, a -90 and a +90 phase shifter of πand T-type. In this paper, that of 10 elements is newly presented. Frequency characteristics of the two 180 Wilkinson dividers and those of a rat-race divider known as an out of phase circuit are discussed. Key-Words: Wilkinson divi...

Resistive power divider for magneto-inductive waveguides

Addressing the need for passive magneto-inductive components, a lumped-element symmetric power divider has been designed and realised for a magneto-inductive cable with the resonant frequency of 95 MHz and the passband between 73 and 174 MHz. In agreement with the theory, the measured coupling loss is 6 dB for most of the passband independent of the input port. Having proved useful for magneto-...
