Adjustable, High-Linearity,

SiGe Dual-Band LNA/Mixer ICs

General Description

Features

The MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/

MAX2327 high-performance silicon germanium (SiGe)

receiver front-end ICs set a new industry standard for

low noise and high linearity at a low supply current. This

family integrates a variety of unique features such as an

LO frequency doubler and divider, dual low-noise

amplifier (LNA) gain settings, and a low-current paging

mode that extends the handset standby time.

ꢀ Ultra-High Linearity at Ultra-Low Current and

Noise

ꢀ +2.7V to +3.6V Operation

ꢀ Pin-Selectable Low-Gain Mode Reduces Gain by

17dB and Current by 3mA

ꢀ Pin-Selectable Paging Mode Reduces Current

Draw by 6mA when Transmitter Is Not in Use

The MAX2320 family includes six ICs: four operate at

both cellular and PCS frequencies, one operates at cel-

lular frequencies, and one at PCS frequencies (see

Selector Guide). Each part includes an LNA with a high

input third-order intercept point (IIP3) to minimize inter-

modulation and cross-modulation in the presence of

large interfering signals. In low-gain mode, the LNA is

bypassed to provide higher cascaded IIP3 at a lower

current. For paging, a low-current, high-gain mode is

provided.

ꢀ LO Output Buffers

ꢀ LO Frequency Doubler (MAX2321)

ꢀ LO Frequency Divider (MAX2326)

ꢀ 0.1µA Shutdown Current

ꢀ 20-Pin TSSOP-EP Package

Ordering Information

The CDMA mixers in cellular and PCS bands have high

linearity, low noise, and differential IF outputs. The FM

mixer is designed for lower current and a single-ended

output.
