Development of a 20 kW Solid State Power Amplifier (SSPA), at 352 MHz, is in progress at RRCAT. This design uses radial dividing and combining architecture. As a part of this system, two high power (4 kW) combiners have been designed and developed. First one is 8 way with output ports in opposite but parallel direction to input port. Second one is 16 way with radial output ports. This paper des...

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....

The most important advantage of voltage dividers over traditional voltage transformers is that voltage dividers do not have an iron core with non-linear hysteresis characteristics. The voltage dividers have a linear behavior with respect to over-voltages and a flat frequency response larger frequency range. The weak point of a voltage divider is the influence of external high-voltage (HV) and e...

DESIGN, ANALYSIS, AND CONSTRUCTION OF AN EQUAL SPLIT WILKINSON POWER DIVIDER Logan J. Berens, B.S. Marquette University, 2012 The Wilkinson power divider is a well known device in the RF/microwave community used for splitting or combining signals. It is composed of simple transmission lines and a resistor, and takes advantage of the properties of quarterwavelength transmission line sections to ...

A novel design of a dual-frequency unequal power divider is presented. The design is optimized using a genetic algorithm based method in order to satisfy several requirements at two given frequencies. The method considers realistic conditions, since it assumes lossy transmission lines and unmatched real or frequency-dependent complex loads. The method can be applied in a wide range of applicati...
