1. A receive system for performing carrier aggregation (CA) and multiple input multiple output (MIMO) operation at millimeter wave (mmW) frequencies, comprising:
a phased array having a plurality of groupings each having a pair of sub array structures, each sub array structure having a plurality of phased array elements and a multiplexer, each phased array element coupled to an antenna element, each phased array element having a low noise amplifier (LNA) and a phase shifter (PS), the plurality of groupings comprising a first high band (HB) grouping and a first low band (LB) grouping;
a downconverter circuit selectively connected to each sub array structure in the first high band (HB) grouping and the first low band (LB) grouping, each downconverter circuit having a radio frequency (RF) amplifier, a mixer, an intermediate frequency (IF) amplifier, and a filter; and
a combining circuit connected to each of the downconverter circuits selectively connected to the first high band (HB) grouping and the first low band (LB) grouping, the combining circuit configured to provide signals from each downconverter circuit to an intermediate frequency (IF) port.
