SiGe, High-Linearity, 2300MHz to 4000MHz
Upconversion/Downconversion Mixer with LO Buffer
General Description
The MAX2044 single, high-linearity upconversion/down-
conversion mixer provides +32.5dBm input IP3, 8.5dB
noise figure, and 7.7dB conversion loss for 2300MHz
to 4000MHz LTE, WiMAXK, and MMDS wireless infra-
structure applications. With an ultra-wide 2600MHz to
4300MHz LO frequency range, the MAX2044 can be
used in either low-side or high-side LO injection archi-
tectures for virtually all 2.5GHz and 3.5GHz applications.
In addition to offering excellent linearity and noise
performance, the MAX2044 also yields a high level of
component integration. This device includes a double-
balanced passive mixer core, an LO buffer, and on-chip
baluns that allow for single-ended RF and LO inputs.
The MAX2044 requires a nominal LO drive of 0dBm,
and supply current is typically 138mA at VCC = 5.0V or
121mA at VCC = 3.3V.
The MAX2044 is pin similar with the MAX2029/MAX2031
650MHz to 1000MHz mixers and the MAX2039/MAX2041/
MAX2042 1700MHz to 3000MHz mixers, making this
entire family of up/downconverters ideal for applica-
tions where a common PCB layout is used for multiple
frequency bands.
The MAX2044 is available in a compact 20-pin thin QFN
(5mm x 5mm) package with an exposed pad. Electrical
performance is guaranteed over the extended -40NC to
+85NC temperature range.
