Maxim Integrated MAX2683

The MAX2683 is optimized for downconversion to IF frequencies between 100MHz and 400MHz, and allows both high-side and low-side local oscillator (LO) injection. The MAX2684 is optimized for IF frequencies between 800MHz and 1000MHz, and allows low-side LO injection. 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.

GENERAL DESCRIPTION

The MAX2683/MAX2684 are super-high-performance, low-cost downconverter mixers intended for wireless local loop (WLL) and digital microwave radio (DMR) applications in the 3.4GHz to 3.8GHz frequency band. A logic-level control enables an internal frequency doubler on both devices, allowing the external LO source to run at full or half frequency. An internal LO filter reduces LO harmonics and spurious mixing. 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.
