摘要： Embodiments of a communication circuit are described. This communication circuit includes an input node (212) to receive a set of data symbols and a partitioner (216) coupled to the input node. The partitioner is to divide the set of data symbols into M irregular subgroups of data symbols, a given one of which includes non-consecutive data symbols in the set of data symbols. Moreover, this given irregular subgroup of data symbols includes at least two pairs of adjacent data symbols having different inter-data-symbol spacings in the set of data symbols. This communication circuit also includes M modulators (218-1, 218-N1) coupled to the partitioner, where the given irregular subgroup of data symbols is coupled to a given modulator in the M modulators. Furthermore, the communication circuit includes M output nodes, where a given output node in the M output nodes is coupled to the given modulator and is to couple to an antenna element in M antenna elements (226).

摘要： A fully integrated CMOS multi-element phased-array transmitter (transmitter) includes, in part, on-chip power amplifiers (PA), with integrated output matching. The transmitter is adapted to be configured as a two-dimensional 2-by-2 array or as a one dimensional 1-by-4 array. The transmitter uses a two step up-conversion architecture with an IF frequency of 4.8 GHz. Double-quadrature architecture for the up-conversion stages attenuates the signal at image frequencies. The phase selectors in each transmitter path have independent access to all the phases of the VCO. The double quadrature architecture results in two sets of phase selectors for each path, one for the in-phase (I) and one for the quadrature phase (Q) of the LO signal. The phase selection is done in two stages, with the first stage determining the desired VCO differential phase pair and the next stage selecting the appropriate polarity. An on-chip Balun is used for differential to single-ended conversion.
