Abstract A power upgrade of the existing 8-kW solid-state driver amplifier is required for acceleration high intensity proton beams on J-PARC 3-GeV Rapid Cycling Synchrotron. The development a 25-kW with gallium nitride (GaN) HEMTs, based 6.4-kW modules ongoing. combiner key component to achieve such output over wide bandwidth multi-harmonic RF operation. This paper presents preliminary design ...

Training an ensemble of neural networks is an interesting way to build a Multi-net System. One of the key factors to design an ensemble is how to combine the networks to give a single output. Although there are some important methods to build ensembles, Boosting is one of the most important ones. Most of methods based on Boosting use an specific combiner (Boosting Combiner). Although the Boosti...

Nowadays, fiber laser has been widely used in industrial processing, especially welding, cutting and other fields, the appearance of adjustable ring-mode improves effectively quality processing. In this paper, a (6 + 1) × 1 signal combiner is developed based on technology cladding corrosion. The test results show that under same injection condition, beam transmitted through central port degrade...

This paper describes design all-optical logic gates NAND, NOR, XNOR using...

This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five resistors is selected and optimized based on Quasi Newton method. Then the Defected Microstrip Structure (DMS) and Defected Ground Structure (DGS) is used to obtain better tra...

A (k, l)-robust combiner for collision resistant hash functions is a construction, which takes l hash functions and combines them so that if at least k of the components are collision resistant, then so is the resulting combination. A black-box (k, l)-robust combiner is robust combiner, which takes its components as black-boxes. A trivial black-box combiner is concatenation of any (l−k+1) of th...

We report a GaN-based broadband power amplifier using AlGaN/GaN-HEMTs, grown on sapphire substrates, as the active devices. The circuit topology used novel LCRmatching networks in a 4-way binaryWilkinson combiner structure. The devices were flip-chip bonded onto the AlN circuit for thermal management. Using devices with 0.7-pm gate length and 4-mm gate width, a small-signal gain of 7 dB was obt...

A low-power and high-speed frequency multiplier for a delay-locked loop-based clock generator is proposed to generate a multiplied clock with different range of frequencies. The modified edge combiner consumes low power and achieves a high-speed operation. The proposed frequency multiplier overcomes a deterministic jitter problem by reducing the delay difference between positiveand negative-edg...

A customized laser combiner was designed and constructed for dual channel single molecule imaging. The feasibility of a combiner-incorporated imaging system was demonstrated in studies of single molecule FRET. Distance rulers made of dual-labeled dsDNA were used to evaluate the system by determining the distance between one FRET pair. The results showed that the system is sensitive enough to di...

This paper presents a hybrid scheme using a Fourier Linear Combiner and a fuzzy expert system for the classification of transient disturbance waveforms in a power system. The captured voltage or current waveforms are passed through a Fourier Linear Combiner block to provide normalized peak amplitude and phase at every sampling instant. The normalized peak amplitude and computed slope of the wav...
