General Description

The MAX2387/MAX2388/MAX2389 low-noise amplifier

(LNA), downconverter mixers designed for W-CDMA

applications, are ideal for ARIB (Japan) and ETSI-

UMTS (Europe) based systems. The MAX2387/

MAX2388/MAX2389 feature ultra-low current consump-

tion and exceptionally low noise figures in ultra-small

packages.

The MAX2387/MAX2388 include an LNA, a downcon-

verter mixer, and a local-oscillator (LO) buffer. The

MAX2389 has an LNA and mixer, but minimizes current

consumption by omitting the LO buffer. For all devices,

the LNA and downconverter mixers are optimized for

the 2110MHz to 2170MHz band. All devices feature a

high-gain mode and a low-gain mode of LNA operation.

The MAX2387 has a 32dB gain step, and the

MAX2388/MAX2389 have an 18dB gain step. All ICs

include a shutdown mode, powering down the IC dur-

ing the front-end receiver’s idle periods.

The mixer 3rd-order nonlinearity performance is set

using an external biasing resistor. For the MAX2387/

MAX2388, mixer performance is optimized for a

-10dBm typical drive at the LO buffer input port. The

Ordering Information

MAX2389 mixer performance is optimized for a

-4dBm typical drive at the LO input port. The LO port

for all versions is configurable for either single-ended or

differential operation.

These devices operate from a +2.7V to +3.3V single sup-

ply and are available in ultra-small (3mm ? 3mm) 12-pin
