MAXIM MAX2044 Technical data
19-5002; Rev 0; 10/09
SiGe, High-Linearity, 2300MHz to 4000MHz
Upconversion/Downconversion Mixer with LO Buffer
General Description
The MAX2044 single, high-linearity upconversion/downconversion mixer provides +32.5dBm input IP3, 8.5dB
noise figure, and 7.7dB conversion loss for 2300MHz
to 4000MHz LTE, WiMAXK, and MMDS wireless infrastructure 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 architectures 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 doublebalanced 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 applications 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.

Note 1: Based on junction temperature TJ = TC + (BJC x VCC x 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 +150NC.
Note 2: Junction temperature TJ = TA + (BJA x VCC x ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150NC.
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: TC is the temperature on the exposed pad of the package. TA is the ambient temperature of the device and PCB.
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 9: Maximum reliable continuous input power applied to the RF or IF port of this device is +20dBm from a 50I source.
Note 10: Not production tested.
Note 11: Measured with external LO source noise filtered so 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 Application Note 2021: Specifications and
Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers.
