Abstract
Methods and apparatuses for providing a tunable Wilkinson power splitter are presented. According to one aspect, the tunable splitter includes tunable branches realized via lumped elements that provide controlled impedance and phase at different selectable center frequencies of operation. For each of the center frequencies, the tunable Wilkinson splitter has a performance according to a corresponding fixed center frequency Wilkinson power splitter provided by a relatively narrow instantaneous bandwidth. Over a number of the center frequencies supported, performances of the tunable Wilkinson splitter overlap to provide a combined performance having a desired wider bandwidth. According to another aspect, each of the tunable branches includes an LC network that includes tunable capacitors and inductors. One or more of the tunable Wilkinson power splitters can be cascaded to provide a performance according to a wider instantaneous bandwidth.
