This paper proposes a new design of an electromagnetic interference wideband filtering power divider (FPD) with wide stopband based on the genetic algorithm (GA). A set data structures is constructed by describing corresponding connection method between basic units and their electrical parameters in three-port design. Then, GA used to find appropriate topology parameters, including isolation re...

A new broadband in-phase power divider based on multilayer technology is presented. A simple design procedure is developed for the proposed multilayer power divider. An S-band four-way multilayer power divider was designed and measured. The simulated results are compared with the measured data, and good agreement is reported. The measured 15 dB return loss bandwidth is demonstrated to be about ...

Abstract—A compact dual-band power divider for GSM/DCS applications is proposed in this letter. Novel planar artificial transmission lines are applied to miniaturize the power divider and achieve wideband response. The proposed dual-band power divider is about 37% of conventional one. The design principle, simulated and measured results are all discussed. The measured results show that good per...

Background and Objectives: In this paper, a new design strategy was proposed in order to enhance bandwidth and efficiency of power amplifier. Methods: To realize the introduced design strategy, a power amplifier was designed using TSMC CMOS 0.18um technology for operating in the Ka band, i.e. the frequency range of 26.5-40GHz. To design the power amplifier, first a power divider (PD) with a ver...

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...

This paper proposes a multiway power divider for wideband (4:1) beamforming arrays. The divider’s input reflection characteristic (S11) is achieved using a multisection stepped-impedance transformer. Moreover, the divider’s isolation (S32) bandwidth is increased by incorporating inductors and capacitors in addition to the conventional resistor only isolation networks of the divider. The analysi...
