“…Initially, for kW power level, Gysel combiner (Gysel 1975) was developed and tested; however later on due to fabrication difficulties, it was dropped. Among different combining choices, radial combiners (Swift 1988), where power combining or dividing action is achieved in a single step, was found as an efficient candidate for combining n (>2) amplifiers. The tree-structures, for large n, have the disadvantage of utilizing a multitude of connecting transmission line segments, which add losses.…”

Radio frequency and Microwave (RFM) infrastructure test facility is under development at RRCAT for evaluating and powering, subsystems of particle accelerator. As a part of this facility, design of 20-30 kW UHF solid state power amplifiers is in progress. For this work, design procedure has been formulated for the development of solid state amplifier modules, radial combiner, divider and directional coupler; with specifications suited to RFM power system for particle accelerator. Methodology has been demonstrated by developing two different compact amplifiers with power output of 2 kW each, operating at 352 MHz and 505.8 MHz, respectively. This paper describes underlying design principles and indigenous development of these amplifiers, consisting of 270-300 W amplifier modules, 8-way 2 kW radial combiner/divider and directional couplers. Design methodology for power combiner has been extended by physically realizing higher power (4 kW) 16-way power combiner and 2-way combiner (8 kW) for higher power (8 kW) amplifier configuration planned. Simple design, indigenous technology, high efficiency and ease of fabrication, are the main features of this design.

Abstract-A simple equivalent circuit model with empirical equations describing the peripheral feeding ports of conical line power combiners is presented. The model allows the entire structure to be designed using transverse electromagnetic circuit theory without the need for any full-wave simulations. A summary of the model extraction process is given and the accuracy of the proposed model is confirmed by favorable comparisons with full-wave simulations. The circuit based design method is used to design a compact conical line combiner showing measured performance similar to the current state of the art combiners in this technology, while being significantly smaller.

“…Therefore, maintaining symmetry among the scattering parameters of ports will be difficult. Combiners with coaxial output are widely studied so far [1][2][3][4][5]. In works related to combiners with a rectangular waveguide output, usually the input ports are not of coaxial type [6].…”
