“…The isolation resistor R1 is placed in between the two output branches to provide the better isolation. The line impedance and isolation resistor values can be calculated by using the design equations shown in below (1) - (5). An additional isolation resistor R2 is inserted at the end of transmission lines is shown in Fig 2. It provides isolation among the Ultrawideband range…”

“…In case of PAA power dividers plays a major role and the essential principle of the power divider or power splitter is to separate the given input signal at the input port into two or more output signals at the respective output ports with equal or unequal power distribution over the operating frequency range. Depending upon the range of operation and splitting ratio of input signal (equal or unequal) various power dividers [1][2][3][4][5][6][7] are used in RF Communication devices. A distinct unequal, planar, wideband, ultra-wideband power dividers has been presented in the literature with their own frequency operation and structure [1][2][3][4][5][6][7].…”

In this article, a compact unequal, planar Wilkinson power divider with ultra-wideband operation is proposed. The composed power divider having the size of 11.6 mm × 18.5 mm. It consists of one input and two output branches with individual resistive values. Two isolation resistors are used to provide better isolation between the two output ports. The impedance values of each transmission branch and isolation resistors is varied based on the output power division ratio i.e. (P2/P3). The ADS package simulated results of the designed unequal WPD satisfy the operating range (S11 ≤ -10 dB) from 2.5 GHz to 18 GHz and isolation are obtained over the entire frequency of operation.

“…The authors in Ref. [9] achieved wideband isolation by using coupled lines to match the ports without modifying the isolation network in a conventional WPD. This approach also has the limitation of requiring various TL sections which increases insertion losses and design complexity.…”

This article presents design analyses for achieving an ultrawide isolation bandwidth compensated power divider (CPD). The CPD offers improvement in complexity, size, and insertion when compared with alternative techniques for increasing isolation bandwidth. A prototype CPD with 215 dB isolation bandwidth of 114% was fabricated and measured to validate the analyses. K E Y W O R D S isolation bandwidth, power dividers, Wilkinson dividers

“…To affect the propagation of electromagnetic waves within the structure, photonic crystals are designed with the help of dielectric constant materials in all the three dimensions (1D, 2D & 3D). PCs have great advantages in designing ultra-compacted all optical integrated circuits with significant reduction in the size and power consumption [1][2][3]. The photonic band gap (PBG) is obtained as the result of this periodicity when the transmission light becomes zero at certain frequencies.…”

Abstract. The next generation Photonic Integrated Circuit (PIC) make use of optical power divider for achieving high operating speeds in the field of optical communication. A Wilkinson power divider is designed using 2D Photonic Crystal in this paper. Wilkinson power divider is three port network which is lossy. But when the output ports are matched, it has unique property of becoming losslesss. The divider also achieves isolation between output ports. The power dissipated is from the power that is reflected. The propagation of wave and photonic band gap were obtained by Finite-difference Time-Domain (FDTD).The designed structure has a resonant wavelength of 1550 nm. The simulation is performed using Opti FDTD software. For the two port Wilkinson power divider 55.4% of input power was coupled at the output. For the 4 port 55% of input power was coupled at the output port.
