Abstract: A novel and useful apparatus and method for an image-interferer aware single quadrature RF downconversion (SQRD) low intermediate frequency (LIF) receiver and related power reduction techniques utilized therein. The invention applies zero-margin adaptive transceiver (ZMAT) design principles to considerably reduce the receiver's power consumption in an adaptive fashion in accordance with the instantaneous reception conditions. In a low IF dual-branch (i.e. quadrature) downconversion receiver, the radio monitors the image strength and shuts off the receiver's Q branch (or I branch) when image rejection is not needed (i.e. when the relative image strength is below a threshold), thus significantly reducing power consumption in the RF receiver. A zero IF receiver is switched to a SQRD low IF receiver of lower power consumption when the image interferer strength is low enough to allow for a given required level of performance.
