Abstract
A self-contained radio-frequency device featuring multiple overlapping coupled coil inductors in a planar configuration with overlaps selected for desired coupling between different pairs of coils, wherein the electromagnetic energy of the coils arises substantially only from the coils themselves and affects only the coils themselves. Overlapping configurations provide a compact space-saving form-factor for such a device a variety of applications, including filters, baluns, transformers, matching networks, amplifier stages, distributed amplifiers, and frequency multipliers. Space-saving is achieved by overlapping the coils while controlling the mutual inductance. The planar arrangements are applicable to a variety of technologies, such as integrated circuits (IC, ASIC, RFIC), ceramic multilayer technologies such as low temperature co-fired ceramics (LTCC), and to printed circuit boards (PCB). Planar arrangements of overlapping coils is illustrated with respect to filters, tunable filters and Q-enhanced filters.
