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 ...

As a key component in microwave applications such as antenna feeding network, power distribution network, and array systems requiring beam forming network(BFN) in satellite communication, the power divider/combiner is widely designed and implemented by using various analysis methods[1,2] and various integration method[6-8]. In array systems employing microstrip feeding network, the beam forming...

With the increasing demand for efficient spectrum management, programmable wireless radios can potentially play a key role in shaping our future spectrum use. In this paper, we consider the design of low-power programmable wireless radios based on orthogonal frequency division multiple access (OFDMA). To meet the demands of higher data rate communications, we split OFDMA symbols carrying multiu...

A (k, `)-robust combiner for collision-resistant hash-functions is a construction which from ` hash-functions constructs a hash-function which is collision-resistant if at least k of the components are collisionresistant. One trivially gets a (k, `)-robust combiner by concatenating the output of any ` − k + 1 of the components, unfortunately this is not very practical as the length of the outpu...

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...
