a filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. this design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. the high isolation between output ports is obtained by combining the half mode substrate integrated wa...

a power divider (pd)/ power combiner (pc) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (siw) technology is proposed. an siw cavity is designed to provide a high quality factor filtering response and an smd resistor is attached between two output ports to realize the high isolation. the value of the applied resistor is calculated by using the ...

The goal of the research reported here was the development of a circuitbased modeling procedure for both the passive and active components of a quasi-optical power combiner. Contributions include the development of a multi-port equivalent circuit of a multi-element quasi-optical power combiner. Excellent agreement with experimental results was obtained. Mount independent techniques "were also d...

Introduction: Power amplifiers are a key building block in any radio transceiver, usually necessitating a multi-chip module solution owing to the requirement of a specialised process with high voltage breakdown and low-loss passive components. Several researches have demonstrated that CMOS technology is a viable option for implementation of the power amplifier. Fully integrated transformer base...

This paper examines some relationships between important design parameters in large combiner systems and key performance objectives such as power, efficiency, noise, and graceful degradation. Results are derived for the combining efficiency of general combiner systems, and used to contrast spatial and corporate combiners and identify optimum combiner topology for a given device technology. The ...
