High-Linearity, 815MHz to 1000MHz Upconversion/Downconversion Mixer with LO Buffer/Switch

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 MAX2029 high-linearity passive upconverter or downconverter mixer is designed to provide +36.5dBm IIP3, 6.7dB NF, and 6.5dB conversion loss for an 815MHz to 1000MHz RF frequency range to support GSM/cellular base-station transmitter or receiver applications. With a 570MHz to 900MHz LO frequency range, this particular mixer is ideal for low-side LO injection architectures. For a pin-to-pin-compatible mixer meant for high-side LO injection, refer to the MAX2031 data sheet.

In addition to offering excellent linearity and noise performance, the MAX2029 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 MAX2029 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 100mA.

The MAX2029 is pin compatible with the MAX2039, MAX2041, MAX2042, MAX2044 series of 1700MHz to 2200MHz, 2000MHz to 3000MHz, and 3200MHz to 3900MHz mixers, making this family of passive upconverters and downconverters ideal for applications where a common printed-circuit board (PCB) layout is used for multiple frequency bands.

The MAX2029 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.
