High-Linearity, 1700MHz to 2200MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
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
-40°C to +85°C temperature range.

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.
