Lumped-element Wilkinson power splitters can be used to replace the classical microstrip realization at frequencies from RF to several GHz, where quarter-wave line segments become large.
Several power splitters (two-, three-way, unequal split) employing low-cost SMD passive components have been designed in the 1 GHz band, providing excellent performance, similar to that expected for a transmission line divider for a modest bandwidth. They are also compact, allowing reduced circuit dimensions, and exhibiting a low pass behavior (not repeated at odd multiples of the center frequency), filtering the harmonic components of the input signal. |
