A Power Divider with Adjustable Dividing Ratio
نویسندگان
چکیده
An unequal Wilkinson power divider with adjustable power dividing ratio is proposed. The proposed power divider consists of rectangular defected ground structure (DGS), isolated island in DGS, and varactor diodes. The impedance of the microstrip line greatly increases due to the DGS, and varies because of the varying capacitance of diodes. The measured unequal dividing ratios vary from 1.97–13.4 and 2.25–10.6 when 2and 4-diodes are adopted. key words: defected ground structure, DGS, power dividers

A Novel Approach to the Design of Dual- Band Power Divider with Variable Power Dividing Ratio Based on Coupled-lines
This paper presents an approach to the design of a novel dual-band power divider with variable power dividing ratio. To achieve dual-band operation, a novel dual-band quarter-wave length transformer based on coupled-lines is proposed, which is used to replace the quarter-wave length transformer in Wilkinson power divider. The proposed dual-band power divider features a simple compact planar str...
متن کاملDesign of a Compact Tri-band Power Divider with Unequal Outputs
In this paper, we present a new design of a compact tri-band unequal power divider, which is composed of a circularcoupling power divider and a triple-band resonator. The unequal power dividing characteristic is realized by two circular shaped microstrip lines coupled through a circular shaped slot. The triple-band resonator, which comprises a conventional half-wavelength resonator, a short stu...
متن کاملDual-band Equal/unequal Wilkinson Power Dividers Based on Coupled-line Section with Short-circuited Stub
This paper presents dual-band equal/unequal Wilkinson power dividers based on a coupled-line section with short-circuited stub (called as the “coupled-line section” for short), which consists of a pair of parallel coupled lines and a short-circuited stub. With the analyses of the phase shift and equivalent characteristic impedance, the coupled-line section is used to replace the quarter-wavelen...
متن کاملDesign of Unequal Wilkinson Power Divider for Tri-band Operation
Abstract—This paper presents a novel tri-band unequal Wilkinson power divider. The proposed structure is derived from the conventional unequal Wilkinson power divider by replacing the quarter-wavelength branch lines and quarter-wavelength transformers with the extended T-shaped short stubs and three-section transformers respectively. The first and third operating frequencies of the proposed Wil...
متن کاملDc High-voltage Divider Evaluation Using the Binary Step-up Method
An evaluation technique and traceability for a DC-resistive high-voltage divider was established based on 1 kV, which was traceable to a Josephson voltage standard at the Korea Research Institute of Standards and Science. To do this, the binary step-up method was used to evaluate the voltage-dividing ratio and the voltage coefficient of the divider up to 100 kV. The expanded relative uncertaint...
