MAX2327EUP

Overview

The MAX2327EUP is an adjustable, high-linearity silicon germanium (SiGe) dual-band low-noise amplifier and mixer integrated circuit. Designed for cellular front-ends, it operates across the 800 MHz to 1000 MHz band and the 1800 MHz to 2500 MHz band. The device integrates a local oscillator frequency doubler and divider, along with dual LNA gain settings. It is housed in a 20-TSSOP surface-mount package with a width of 4.40 mm.

Feature Summary

• Integrates dual-band low-noise amplifier and mixer functionality within a single SiGe IC
• Includes internal local oscillator frequency doubler and divider circuits
• Provides selectable dual gain settings for the low-noise amplifier stage

Applications

• CDMA cellular front-end systems
• PCS cellular communication interfaces
• Dual-band wireless receiver architectures

Procurement Notes

Verify that the specific part number matches the required operational bands and package configuration. Confirm that the supplier provides official documentation from Analog Devices or Maxim Integrated. Ensure compatibility with system voltage requirements and interface specifications before integration into the design.

Selection Notes

Select this component when a compact solution for dual-band RF signal conditioning is required. The integrated LO generation reduces external component count. Consider the SiGe technology for its linearity performance in noisy environments. Verify that the TSSOP package fits the available PCB footprint constraints.
