MAX2048ETP+

RF Mixers Overview

The MAX2048ETP+ is a high-linearity upconversion and downconversion mixer manufactured by Analog Devices Inc. (Maxim Integrated). It operates within the frequency range of 1600MHz to 3900MHz, supporting wireless infrastructure applications such as GSM/EDGE, CDMA, TD-SCDMA, WCDMA, LTE, and WiMAX. The device features an ultra-wide local oscillator (LO) frequency range from 1300MHz to 4000MHz, enabling flexible low-side or high-side LO injection architectures. It integrates a double-balanced passive mixer core, an LO buffer, and on-chip baluns for single-ended RF and LO inputs.

RF Mixers Feature Summary

• Integrates a double-balanced passive mixer core with an LO buffer and on-chip baluns
• Supports both upconversion and downconversion operations across a wide frequency band
• Enables flexible system design through ultra-wide LO frequency range compatibility
• Provides high component integration by allowing single-ended RF and LO inputs

RF Mixers Applications

• GSM/EDGE wireless infrastructure systems
• CDMA and TD-SCDMA communication networks
• WCDMA and LTE base station implementations
• WiMAX and MMDS wireless broadband applications

RF Mixers Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the ordering information matches the required pinout and electrical specifications for the target application. Cross-reference the part number with the latest datasheet revisions to avoid discrepancies in performance parameters or packaging details during procurement.

RF Mixers Selection Notes

Select this component when designing systems requiring high linearity and low noise figure in the 1.6GHz to 3.9MHz range. Consider its suitability for applications needing integrated baluns and LO buffers to reduce external component count. Evaluate the power supply requirements and thermal management needs based on the specified operating current at different voltage levels.

RF Mixers Part Context

This device belongs to Maxim Integrated's family of high-performance RF mixers designed for wireless infrastructure. It shares pin compatibility with related models like the MAX2042 and exhibits pin similarity with the MAX2029/MAX2031/MAX2033 and MAX2039/MAX2041 series. This commonality facilitates PCB layout reuse across multiple frequency bands within the same product line.

RF Mixers Replacement Considerations

The MAX2042 is explicitly noted as pin compatible with this device. For applications requiring operation in the 2.0GHz to 3.0GHz range specifically tuned for low-side LO injection, the MAX2042 variant may be considered. Other pin-similar options include the MAX2029, MAX2031, MAX2033, MAX2039, MAX2041, and MAX2044.
