MAX2029ETP+

RF Mixers Overview

The MAX2029ETP+ is a high-linearity passive upconversion and downconversion mixer designed for the 815MHz to 1000MHz RF frequency range. It integrates a double-balanced passive mixer core, a dual-input LO selectable switch, an LO buffer, and on-chip baluns for single-ended inputs. The device provides +36.5dBm IIP3, 6.7dB noise figure, and 6.5dB conversion loss. It operates with a nominal LO drive of 0dBm and draws less than 100mA supply current. The component is housed in a compact 20-pin thin QFN package (5mm x 5mm) with an exposed paddle.

RF Mixers Feature Summary

• Integrates a double-balanced passive mixer core with an LO buffer and selectable switch
• Includes on-chip baluns enabling single-ended RF and LO connections
• Supports low-side LO injection architectures with a 570MHz to 900MHz LO range

RF Mixers Applications

• GSM base-station transmitter applications
• Cellular base-station receiver applications
• Low-side LO injection architectures

RF Mixers Procurement Notes

Verify the specific suffix and RoHS compliance status directly against the manufacturer's official documentation before procurement. Confirm that the required LO drive level and supply current constraints align with the system power budget. Ensure the thermal requirements for the exposed paddle are met by the PCB layout design to maintain performance within the specified temperature range.

RF Mixers Selection Notes

Select this component when a high-linearity mixer with integrated buffering and switching is required for the 815MHz to 1000MHz band. It is suitable for designs needing pin-to-pin compatibility with the MAX2039, MAX2041, MAX2042, and MAX2044 series to facilitate common PCB layouts across multiple frequency bands. Consider the low-side LO injection capability when defining the local oscillator architecture.

RF Mixers Part Context

The MAX2029ETP+ belongs to a family of passive upconverters and downconverters from Analog Devices/Maxim Integrated. This family includes pin-compatible parts such as the MAX2039, MAX2041, MAX2042, and MAX2044, which cover higher frequency ranges from 1700MHz to 3900MHz. This compatibility allows designers to use identical printed-circuit board layouts for different cellular frequency bands.

RF Mixers Replacement Considerations

The MAX2039, MAX2041, MAX2042, and MAX2044 are pin-compatible members of the same product family. These substitutes support higher frequency ranges from 1700MHz to 3900MHz and may be considered if the application requires operation outside the 815MHz to 1000MHz range while maintaining the same PCB footprint.
