MAX2388EGC+T

P1-P3P4-P6P7-P9P10-P11
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
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
leadless packages (QFN).
