The MAX2683/MAX2684 feature an externally adjustable bias control, set with a single resistor, that lets the user trade supply current for linearity to optimize system performance. These devices use a double-balanced Gilbert-cell architecture with single-ended RF and LO inputs and differential open-collector IF output ports. Differential IF ports provide a wideband, flexible interface for either single-ended or differential applications. The MAX2683/MAX2684 operate from a single +2.7V to +5.5V supply. The devices are packaged in an ultrasmall 16-pin TSSOP-EP package with an exposed paddle for optimum performance at 3.5GHz.
