摘要：
A wireless receiver is provided that includes a multi-step gain-control low-noise amplifier (LNA) stage and a mixer stage. The LNA stage is operable to amplify at least one input signal to generate at least one LNA output. The mixer stage is directly coupled to the LNA stage (without an intervening external bandpass filter) and is operable to down-convert the LNA output to generate a mixer output.
