1. An apparatus, comprising:
a first receive path including a first reconfigurable amplifier configured to selectively operate in a cascode mode or a non-cascode mode, the first receive path having an input configured to receive a first intermediate frequency (IF) signal corresponding to a first radio frequency (RF) signal and a second IF signal corresponding to a second RF signal either simultaneously or individually;
a second receive path including a second reconfigurable amplifier configured to selectively operate in the cascode mode or the non-cascode mode, the second receive path having an input configured to receive a third IF signal corresponding to the first RF signal and a fourth IF signal corresponding to the second RF signal either simultaneously or individually, wherein the first receive path and the second receive path have a common output;
a first mixer coupled to the common output, wherein the first mixer is configured to frequency down-convert the first IF signal and the third IF signal; and
a second mixer coupled to the common output, wherein the second mixer is configured to frequency down-convert the second IF signal and the fourth IF signal.
