Introduction

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. 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. 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.

Features

• Externally adjustable bias control, set with a single resistor, allowing users to trade supply current for linearity to optimize system performance
• 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
• Operate from a single +2.7V to +5.5V supply
• Packaged in an ultrasmall 16-pin TSSOP-EP package with an exposed paddle for optimum performance at 3.5GHz

Applications

• Wireless Local Loop (WLL)
• Digital Microwave Radio (DMR)
• Wireless Broadband Access
