Planar, lumped element, matched N-way power divider

摘要

An N-way, lumped element, matched, isolated branch power divider in planar form is disclosed. Lumped inductors are disposed on the top surface of a dielectric substrate, an isolation resistor network is disposed on the bottom surface of the substrate and the substrate is suspended above a ground conductor by lumped element capacitors. The capacitance values of the capacitors and the inductance values of the inductors are selected to provide between the common terminal and each branch terminal a lumped element &pgr; network transmission line having a phase shift of about 90° at frequencies within an operating range of frequencies.
