General Description
The MAX2032 high-linearity passive upconverter or
downconverter mixer is designed to provide +33dBm
IIP3, 7dB NF, and 7dB conversion loss for a 650MHz to
1000MHz RF frequency range to support a multitude of
base-station applications. With a 650MHz to 1250MHz
LO frequency range, this particular mixer is ideal for
high-side LO injection architectures. For a pin-to-pincompatible mixer meant for low-side LO injection, refer
to the MAX2029.
In addition to offering excellent linearity and noise performance, the MAX2032 also yields a high level of component integration. This device includes a doublebalanced passive mixer core, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also
integrated to allow for a single-ended RF input for
downconversion (or RF output for upconversion) and
single-ended LO inputs. The MAX2032 requires a nominal LO drive of 0dBm, and supply current is guaranteed
to be below 100mA.
The MAX2032 is pin compatible with the MAX2039/
MAX2041 1700MHz to 2200MHz mixers, making this
family of passive upconverters and downconverters
ideal for applications where a common PCB layout is
used for both frequency bands.
The MAX2032 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed pad.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.

Typical Application Circuit
, VCC= 4.75V to 5.25V, no RF signals applied, TC= -40°C to +85°C. IF+ and IF- are DC grounded through an
IF balun. Typical values are at V
CC
= 5V, TC= +25°C, unless otherwise noted.)
RECOMMENDED AC OPERATING CONDITIONS
Note 1: Maximum, reliable, continuous input power applied to the RF and IF port of this device is +12dBm from a 50Ω source.
Note 2: Based on junction temperature T
J
= TC+ (θJCx VCCx ICC). This formula can be used when the temperature of the exposed
pad is known while the device is soldered down to a PCB. See the
Applications Information
section for details. The junction
temperature must not exceed +150°C.
Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial
.
Note 4: Junction temperature T
J
= TA+ (θJAx VCCx ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150°C.
Note 5: T
C
is the temperature on the exposed pad of the package. TAis the ambient temperature of the device and PCB.
