Abstract: A radio-frequency integrated chip (RFIC) is described which provides a number of low noise amplifiers (LNAs) and load circuits. The low noise amplifiers are organized in groups. In some embodiments, a load circuit may be dedicated to a group or shared between groups. The RFIC includes an LNA group including a plurality of LNAs configured to amplify carrier signals related to a plurality of frequency bands, a second LNA group configured to amplify a plurality of second carrier signals, a first load circuit group dedicated to the first LNA group, a second load circuit group dedicated to the second LNA group, and a third load circuit group shared between the first LNA group and the second LNA group. In some embodiments the third load circuit group adaptively performs frequency down-conversion on a carrier signal amplified by at least one of the first LNA group and the second LNA group.
