General Description
The MAX2039 high-linearity passive upconverter or
downconverter mixer is designed to provide 7.3dB NF
and a 7.1dB conversion loss for an RF frequency range
of 1700MHz to 2200MHz to support UMTS/WCDMA,
DCS, and PCS base-station transmitter or receiver
applications. The IIP3 is typically +34.5dBm and
+33.5dBm for downconversion and upconversion oper-
ation, respectively. With an LO frequency range of
1500MHz to 2000MHz, this particular mixer is ideal for
low-side LO injection architectures. (For a pin-to-pin-
compatible mixer meant for high-side LO injection, con-
tact the factory.)
In addition to offering excellent linearity and noise per-
formance, the MAX2039 also yields a high level of com-
ponent integration. This device includes a
double-balanced 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 MAX2039 requires a
nominal LO drive of 0dBm, and supply current is guar-
anteed to be below 135mA.
The MAX2039 is pin compatible with the MAX2031
815MHz to 995MHz mixer, making this family of passive
upconverters and downconverters ideal for applications
where a common PC board layout is used for both fre-
quency bands.
The MAX2039 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
-40C to +85C temperature range.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
Guaranteed by design and characterization.
Note 2:
All limits include external component losses. Output measurements taken at IF port for downconverter and RF port for
upconverter from the Typical Application Circuit.
Note 3:
Operation outside this range is possible, but with degraded performance of some parameters.
Note 4:
Compression point characterized. It is advisable not to continuously operate the mixer RF or IF input above +15dBm.
Note 5:
Measured with external LO source noise filtered such that the noise floor is -174dBm/Hz. This specification reflects the
effects of all SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.
