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 operation,
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, contact
the factory.)
In addition to offering excellent linearity and noise performance,
the MAX2039 also yields a high level of component
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 guaranteed
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 frequency
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.
