Abstract

This paper presents a novel wideband filtering power divider with designable bandwidth and high port isolation, developed for RF energy harvesting applications. Two classes of structures integrate different shared networks with impedance transformers in their filtering branches to realize Chebyshev transformer functions. This synthesis approach allows for precise control over the bandwidth and return loss (RL). Furthermore, high isolation is achieved by incorporating two resistors between the two output ports. Measured results demonstrate a wide operating band 103.7%, and high isolation level better than 25 dB of the bandwidth.
