Overview
The MAX2359ETI+ is an RF front-end integrated circuit designed for PCS band applications, operating within a frequency range of 1.93 GHz to 1.99 GHz. It integrates a Low Noise Amplifier (LNA) and a mixer in quadruple-mode configuration. The device functions with a supply voltage between 2.7 V and 3.3 V. It is housed in a 28-pin TQFN-EP package with exposed pad, suitable for surface mount installation.
Feature Summary
- Integrates LNA and mixer functionality for efficient signal processing
- Supports quadruple-mode operation for PCS band frequencies
- Designed for compact surface-mount PCB layouts
Applications
- PCS band wireless communication systems
- Mobile phone receiver front-ends
- RF signal downconversion modules
Procurement Notes
Verify component status carefully as the MAX2359ETI+T variant is listed as obsolete by Analog Devices. Confirm availability through authorized distributors or secondary market suppliers. Ensure the specific suffix matches the required packaging format, as tube and tape-and-reel variants exist. Check for end-of-life notices prior to final design commitment.
Selection Notes
Select this component for PCS band applications requiring integrated low-noise amplification and mixing. Consider the 28-TQFN package constraints for thermal management and layout. Verify compatibility with the system's required supply voltage range of 2.7 V to 3.3 V. Evaluate alternative active parts if long-term supply stability is critical due to potential obsolescence.
Part Context
This part belongs to the Maxim Integrated RF front-end family, specifically targeting cellular communication bands. It serves as a single-chip solution for reducing component count in receiver chains. The device utilizes silicon technology and is compliant with RoHS standards where applicable.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The MAX2359ETI+T variant is explicitly marked as obsolete. Designers should consult official Analog Devices resources for current lifecycle status and potential next-generation replacements.
