SiGe High-Linearity, 2000MHz to 3000MHz

Upconversion/Downconversion Mixer with LO Buffer

General Description

The MAX2042 single, high-linearity upconversion/down­conversion mixer provides +36dBm IIP3, 7.3dB noise fig­ure, and 7.2dB conversion loss for 2000MHz to 3000MHz
WCS, LTE, WiMAXK, and MMDS wireless infrastructure
applications. With a wide LO frequency range of 1800MHz
to 2800MHz, this particular mixer is ideal for low-side LO
injection receiver and transmitter architectures. High-side
LO injection is supported by the MAX2042A, which is pin­pin and functionally compatible with the MAX2042.

In addition to offering excellent linearity and noise
performance, the MAX2042 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 MAX2042 requires a nominal LO drive of 0dBm,
and supply current is typically 138mA at VCC = +5.0V or
120mA at VCC = +3.3V.

The MAX2042 is pin compatible with the MAX2042A
2000MHz to 3900MHz mixer. The device is also pin simi­lar with the MAX2029/MAX2031 650MHz to 1000MHz
mixers, the MAX2039/MAX2041 1700MHz to 3000MHz
mixers, and the MAX2044/MAX2044A 3000MHz to
4000MHz mixers, making this entire family of up/down­converters ideal for applications where a common PCB
layout is used for multiple frequency bands.

The MAX2042 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.

Characteristics.

Note 7: All limits reflect losses of external components, including a 0.5dB loss at fIF = 300MHz due to the 1:1 impedance trans-

former. Output measurements were taken at IF outputs of the Typical Application Circuit.

Note 8: 100% production tested for functional performance.
Note 9: Measured with external LO source noise filtered so 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 Application Note 2021: Specifications and
Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers.

Note 10: Maximum reliable continuous input power applied to the RF port of this device is +20dBm from a 50I source.
