SiGe High-Linearity, 2000MHz to 3000MHz Upconversion/Downconversion Mixer with LO Buffer

Industry's Highest Performing, Fully Integrated SiGe Passive Mixer, Featuring Superior IP3, 2RF - 2LO and LO ± 2IF Performance

Please check latest availability status for a specific part variant.


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, WiMAX™, 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 pin-pin 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 double-balanced 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 -40°C to +85°C temperature range.
