MAX2042ETP+

RF Mixers Overview

The MAX2042ETP+ is a SiGe high-linearity upconversion/downconversion mixer with an integrated LO buffer, designed for RF applications. It operates within a frequency range of 2000MHz to 3000MHz. Key electrical specifications include an input IP3 of +36dBm, a noise figure of 7.3dB, and a conversion loss of 7.2dB. The device requires a nominal LO drive of 0dBm and draws typical supply currents of 122mA at VCC = 3.3V or 140mA at VCC = 5.0V. It is housed in a compact 20-pin TQFN package (5mm x 5mm) with an exposed pad and is guaranteed to operate over an extended temperature range of -40°C to +85°C.

RF Mixers Feature Summary

• Integrates a double-balanced passive mixer core, LO buffer, and on-chip baluns for single-ended RF and LO inputs.
• Delivers high linearity performance with +36dBm input IP3 and low noise figure of 7.3dB.
• Supports flexible architecture with ultra-wide LO frequency range capabilities for various injection schemes.

RF Mixers Applications

• GSM/EDGE wireless infrastructure
• CDMA and TD-SCDMA systems
• WCDMA and LTE networks
• WiMAX and MMDS applications

RF Mixers Procurement Notes

Verify the specific suffix 'ETP+' against the manufacturer's official ordering guide to confirm package type and tape/reel configuration. Ensure the component matches the required RoHS compliance status if applicable. Cross-reference the part number with the latest datasheet revision to confirm pinout compatibility with existing designs, particularly when replacing older variants like the standard MAX2042. Confirm that the supplier provides valid traceability documentation for the silicon die.

RF Mixers Selection Notes

Select this component for designs requiring high linearity in the 2GHz to 3GHz band with minimal external components due to integrated baluns. Consider the power consumption requirements, as the device draws approximately 122mA to 140mA depending on the supply voltage. Evaluate thermal management needs given the small TQFN package size and exposed pad design. Ensure the local oscillator drive level meets the specified 0dBm requirement for optimal performance.

RF Mixers Part Context

This device belongs to Maxim Integrated's family of upconversion/downconversion mixers, offering pin compatibility with the MAX2042 and pin similarity to the MAX2029/MAX2031/MAX2033 and MAX2039/MAX2041 series. This commonality facilitates PCB layout reuse across multiple frequency bands. The MAX2042A variant offers a wider frequency range (1600MHz to 3900MHz), while the MAX2042 focuses on the 2000MHz to 3000MHz segment.

RF Mixers Replacement Considerations

The MAX2042 is pin compatible. The MAX2042A is functionally similar but covers a wider frequency range (1600MHz to 3900MHz). Other pin-similar options include the MAX2029, MAX2031, MAX2033, MAX2039, MAX2041, and MAX2044, though these cover different frequency bands.
