Seven Ports Power Divider with Various Power Division Ratios
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...
متن کاملPower Divider with Arbitrary Power Ratio and Arbitrary Ripple Level Using Filter Synthesis Techniques
A novel type of power divider, featuring arbitrary power ratio and arbitrary ripple level, is proposed. This divider consists of a two-port filtering structure connected to a circulator and is straightforwardly designed using microwave filter synthesis techniques. An example is provided, with low-pass domain synthesis and experimental divider demonstration at the Xband, after low-pass to bandpa...
متن کاملCompact Wideband Gysel Power Divider with Arbitrary Power Division Based on Patch Type Structure
A novel Gysel power divider based on patch type structure is presented in this paper. The proposed power divider possesses broad bandwidth, small physical occupation and arbitrary power division. More than 30% bandwidth enhancement is achieved based on the −15 dB input return loss criteria, while 55% size reduction is realized compared with conventional Gysel power divider. What’s more, flat di...
متن کاملA novel tri-band T-junction impedance-transforming power divider with independent power division ratios
In this paper, a novel L network (LN) is presented, which is composed of a frequency-selected section (FSS) and a middle stub (MS). Based on the proposed LN, a tri-band T-junction power divider (TTPD) with impedance transformation and independent power division ratios is designed. Moreover, the closed-form design theory of the TTPD is derived based on the transmission line theory and circuit th...
متن کاملA Triangular Wilkinson Power Divider with Spaced Output Ports
This paper proposes an idea to modify the conventional Wilkinson power dividers to have physically spaced output ports. The well-known internal resistor of Wilkinson power divider is now connected to output ports by two additional transmission lines to create a triangular shape power divider. Several modified power dividers are designed at frequency of 1.0 GHz and one of them is fabricated and ...
