3.5GHz Downconverter Mixers

with Selectable LO Doubler

General Description

Features

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) injec-

tion. 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 exter-

nal LO source to run at full or half frequency. An internal

LO filter reduces LO harmonics and spurious mixing.

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 per-

formance. 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 inter-

face for either single-ended or differential applications.

ꢀ +2.7V to +5.5V Single-Supply Operation

ꢀ Ultra-Small 16-Pin TSSOP-EP Package

The MAX2683/MAX2684 operate from a single +2.7V to

+5.5V supply. The devices are packaged in an ultra-

small 16-pin TSSOP-EP package with an exposed pad-

dle for optimum performance at 3.5GHz.
