Abstract

See full text

Apparatus and methods are provided for coupling RF signals. A lattice coupler design incorporating a pair of shunt inductors provides (i) a virtual ground for biasing and (ii) improved performance characteristics, in both splitter and combiner configurations. Magnetic coupling between the shunt inductors can be selected to maintain improved performance characteristics over a wide bandwidth, while retaining compactness and high efficiency. A design procedure, variations, and results are disclosed.
