In this paper, an isolation enhanced multiway power divider for wideband beamforming array is proposed. This method is based on the concept which converts the divider into multi-section stepped impedance transformer. In addition to this scheme, lumped inductors and capacitors are incorporated in isolation networks to enhance the isolation bandwidth of the divider. In/Output reflection and isola...

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....

A generalized two-way coupled-line power divider with extended ports for dual band is proposed in this paper. The power divider is composed of two section coupled-lines, one conventional transmission line, and an isolation resistor, and employs extension of a transmission line or coupled-line at each port. The design equations are obtained based on evenand odd-mode analysis, and analytical idea...

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...

In this paper, a planar three-way power divider with compact size is presented using quarter-wave long five-conductor couple line. It is analytically proved that the proposed structure allows the performance of three-way power dividers. Based on the derived equations and simulation, the three-way power divider is designed and measured at 2.0GHz. The measurement shows excellent performance with ...

This paper presents implementation of a high speed, low noise and low power frequency divider based on current mode logic and cascade connection of divide-by-2/3 cells for high division range. The proposed divider is optimized for high frequency and low power operation. Integration of the proposed divider in a frequency synthesizer is an attractive option for the ultra-low power carrier signal ...

A seven ports network is proposed to act as a six-way power divider/combiner. The proposed network structure consists of a set of λ/4 planar transmission lines at the design frequency and does not require any isolating resistor. The power divider is capable of providing various power ratios by judicious choice of the transmission lines characteristic impedances. Design equations are derived for...

In this paper, we present a broadband out-of-phase power divider with high power-handling capability. The proposed device consists of several sections of double-sided parallel-strip lines (DSPSLs), a mid-inserted conductor plane, and two external isolation resistors, which are directly grounded for heat sinking. A through ground via (TGV), connecting the top and bottom sides of DSPSLs, is emplo...

The demand for lower cost, lower power, and multiband RF circuits increased in conjunction with need of higher level of integration. In this project a low-power singlephase clock multiband flexible divider for Bluetooth, Zigbee, and Network standard’s 802.15.4 and 802.11 a/b/g Wireless LAN frequency synthesizers is proposed based on pulse-swallow topology and is implemented. The frequency synth...

This letter presents an inductor-loaded 2:1 regenerative frequency divider operating up to 331.2 GHz in an InP HBT process, which, to the best of authors’ knowledge, is the fastest frequency divider reported thus far. On-wafer measurement shows that the divider is operating from 304.8 GHz to 331.2 GHz, with output power from 27 dBm to 12.3 dBm (no probe loss correction), while dissipating 85.5 ...
