MAX2029ETP

RF Mixers Overview

The MAX2029ETP is a high-linearity passive upconverter or downconverter mixer designed for GSM/cellular base-station applications. It operates within an RF frequency range of 815MHz to 1000MHz and supports a local oscillator (LO) frequency range of 570MHz to 900MHz, making it suitable for low-side LO injection architectures. The device provides +36.5dBm input third-order intercept point (IIP3), 6.7dB noise figure (NF), and 6.5dB conversion loss. It requires a nominal LO drive of 0dBm and draws supply current below 100mA from a 4.75V to 5.25V supply. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.

RF Mixers Feature Summary

• Integrates a double-balanced passive mixer core with on-chip baluns for single-ended RF and LO interfaces
• Includes a dual-input LO selectable switch and an LO buffer for flexible architecture support
• Delivers high linearity (+36.5dBm IIP3) and low noise (6.7dB NF) for base-station transmitter/receiver use

RF Mixers Applications

• GSM cellular base-station transmitter applications
• GSM cellular base-station receiver applications
• Low-side LO injection architectures in communication systems

RF Mixers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to restricted availability status. Confirm package integrity and pin alignment for the 20-pin thin QFN (5mm x 5mm) form factor. Ensure thermal management meets the -40°C to +85°C operating range requirements. Cross-reference datasheet revisions to confirm electrical parameter consistency before integration into production designs.

RF Mixers Selection Notes

Select this component for designs requiring high linearity and low noise in the 815MHz to 1000MHz band. It is ideal for low-side LO injection setups; consider the MAX2031 for high-side injection needs. The part is pin-compatible with the MAX2039, MAX2041, MAX2042, and MAX2044 series, facilitating common PCB layouts across multiple frequency bands. Verify supply voltage stability within the 4.75V to 5.25V range during operation.

RF Mixers Part Context

The MAX2029 belongs to a family of passive upconverters and downconverters from Maxim Integrated, designed for cellular infrastructure. It shares pin compatibility with higher-frequency variants like the MAX2039 (1700MHz-2200MHz) and MAX2044 (3200MHz-3900MHz). This compatibility allows designers to reuse printed-circuit board layouts when developing products for different frequency bands, reducing development time and cost while maintaining consistent interface specifications.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers include MAX2031 for high-side LO injection architectures. For multi-band designs requiring pin-to-pin compatibility, consider MAX2039, MAX2041, MAX2042, or MAX2044 series mixers depending on the target frequency range.
