6 TWO-WAY SPLITTER/COMBINER 21B1895
The two-way splitter/combiner 21B1895 consists of a wireline quadrature hybrid mounted on a printed circuit
board. The wireline hybrid is a patented design that consists of a pair of wire centre conductors surrounded by a
continuous dielectric insulator and shielded by a drawn or extruded metal jacket. The resultant construction has
the physical attributes of a semi-rigid coaxial cable and the electric performance of a TEM mode parallel coupled
line coupler. When used as a splitter the input signal is split two ways in equal amplitude signals 90° out of phase
with one another. When used as a combiner the two input signals, which are at 90° out of phase with one another,
are combined to produce an RF output.
