MAX2022

General Description

The MAX2022 low-noise, high-linearity, direct conversion

quadrature modulator/demodulator is designed for single

and multicarrier 1500MHz to 3000MHz UMTS/WCDMA,

LTE/TD-LTE, cdma2000

applications. Direct conversion architectures are advanta-

geous since they significantly reduce transmitter or receiv-

er cost, part count, and power consumption as compared

to traditional IF-based double conversion systems.

In addition to offering excellent linearity and noise perfor-

mance, the MAX2022 also yields a high level of component

integration. This device includes two matched passive mix-

ers for modulating or demodulating in-phase and quadra-

ture signals, three LO mixer amplifier drivers, and an LO

quadrature splitter. On-chip baluns are also integrated

to allow for single-ended RF and LO connections. As an

added feature, the baseband inputs have been matched

to allow for direct interfacing to the transmit DAC, thereby

eliminating the need for costly I/Q buffer amplifiers.

The MAX2022 operates from a single +5V supply. It is

available in a compact 36-pin TQFN package (6mm x

6mm) with an exposed paddle. Electrical performance is

guaranteed over the extended -40°C to +85°C tempera-

ture range.
