Quarter-wavelength N-way power dividers/combiners: historical aspects and new modifications: quarter-wavelength, in-phase, N-way power dividers/combiners are widely used in antenna arrays, power amplifiers and transmitters, mixers, phase shifters and vector modulators. This article briefly reviews the history of known quarter-wavelength power dividers/combiners and presents some novel modifications

The simplest quarter-wavelength, multi-port power divider, known as a Wilkinson divider, (1-2) provides a match at all ports, low loss, in-phase power splitting and high isolation between output ports. Historically, [...]
