Summary: This study proposes a modified Wilkinson Power Divider design that utilizes defected ground structure (DGS) and isolation resistor to achieve improved isolation performance. By incorporating the DGS section between the output ports and soldering the isolation resistor in parallel on the ground plane, the design shows enhanced isolation and return loss, with improved bandwidth compared to other similar works. Measurement results demonstrate significant improvements in isolation and return loss, making the proposed circuits highly desirable for practical applications.

Summary: This work analyzes, designs, and measures compact extended ultra-wideband (UWB) Wilkinson power dividers (WPDs) using tapered transmission lines. The use of carefully designed tapered transmission sections widens the operational bandwidth and reduces the element dimensions. Analytical models and design procedures for simple, compact, and equal and unequal UWB WPDs based on linearly tapered transmission lines are presented. Four different configurations of equal and unequal power dividers are designed. The number and locations of the isolation resistors significantly affect the operational bandwidth of the dividers. The presented designs of the WPDs exhibit superior performance over extended bandwidths, showing good insertion and return loss, good matching, and isolation, over the extended UWB operational bandwidth from 3 GHz to 27 GHz.

Summary: This letter presents a novel lumped element circuit topology for the Wilkinson power divider (WPD) with compact and wideband performance using the bandpass matching network. The design method is inspired by even and odd modes analysis techniques, and the odd-mode circuit has the same grade as the even-mode one by an improved isolation network. The design equations for the proposed WPD are derived by analyzing the Z parameter, and the fabricated power divider based on the GaAs-integrated passive device (IPD) technology shows excellent performance.

Summary: This study investigates the thermal emission and noise performance of silicon-on-insulator (SOI) Wilkinson power dividers (WPDs). The results show that WPDs have a noiseless port and exhibit nontrivial correlations with the thermal signals exiting noisy ports, which can prevent the amplification of thermal noise. Based on this, a modified ring-resonator amplifier is proposed, which significantly improves the signal-to-noise ratio compared to conventional amplifiers. These findings are important for the implementation of SOI-WPDs and their integration in complex photonic networks, especially for mid-IR and quantum photonics applications.
