摘要: Coplanar waveguides have a center signal line and a pair of ground lines on either side formed of a sputtered material such as gold (Au). Such waveguides are subject to what is known as the edge effect at high frequency operation causing currents to concentrate and flow along adjacent edges of the lines. Providing a thicker plated layer only on adjacent edges of the lines provide substantial performance improvements over sputtered lines alone while saving significant amount of Au, thus reducing costs.

摘要: A wireless communication device can include a communication control interface. Beamforming circuitry coupled to the communication control interface receives, over the communication control interface, an index value into a coarse codebook and an offset vector. The index value indicates a value within the coarse codebook, and the offset vector indicates an offset value for a desired beam relative to the index value. The beamforming circuitry determines a new beam direction based on the index value and the offset vector using one of interpolation and extrapolation.
