“…First, the width of transmission line, W for input and output ports are calculated using expression (1) and (2) assuming characteristic impedance, Z 0 = 50 . Next, the width of quadrature transformer transmission line, W1 is obtained by substituiting Z 0 = 50) into expression (1). The length of quadrature transformer is calculated using expression (3) to (5).…”

This paper investigates the performance of two Wilkinson power dividers over a wide band frequencies range from 1 to 13 GHz. The first power divider is designed and developed using single section method while the second power divider is designed using double section method. The main purpose of this study is to determine how much bandwidth improvement can be achieved using double section compared to single section approach. Both designs are investigated using CST Microwave Studio simulation tool. The designs are fabricated on microstrip printed circuit board and measured using vector network analyzer. The simulated and experimental results of both developed dividers are compared and analyzed.

A novel H-K (H shaped-K ports) power divider with manual control was proposed earlier to provide appropriate power division to different parts / segments of networks for their smooth operation. Wilkinson's power dividers are widely used in telecommunication industry; these are simulated and compared with the novel H-K structure. Both designs of Wilkinson's power divider using single section and double section are simulated. A four port 2in  0.9in H-K structure is modeled and analyzed using Ansoft HFSS 11, while Wilkinson's power dividers are simulated using CST Microwave Studio. Comparison in terms of S-parameters for above mentioned structures is also presented in this paper.  Index Points-H-K power divider, Wilkinson's power divider, Ansoft HFSS, 2D S-parametric plots

The analysis of, and derivation of design equations for, a class-B balanced single-ended dual-fed distributed amplifier is presented. This approach allows efficient combining of FET output power without multi-way power combiners, has a good port match, and is easy to design as the gate and drain transmission lines are uniform. The design method ensures that all FETs are optimally used and the efficiency is comparable to that of a conventional single-transistor class-B power amplifier using the same FET type. The design method was applied to a class-B four-FET balanced single-ended dual-fed distributed amplifier designed to operate at 1.8 GHz. Large-signal measurements revealed 8% downward shift of the centre frequency. The measured output power and drain efficiency was consistent with the simulations. The efficiency of the amplifier was comparable to a conventional single-transistor class-B power amplifier using the same type of FET.
