Introduction

The MAX2645 is a versatile, high-linearity, low-noise amplifier designed for 3.4GHz to 3.8GHz wireless local loop (WLL), wireless broadband access, and digital microwave radio applications. The device features an externally adjustable bias control, set with a single resistor, that allows the user to meet minimum linearity requirements while minimizing current consumption. The amplifier’s high-gain, low-noise performance and adjustable input third-order intercept (IP3) allow it to be used as a low-noise amplifier (LNA) in the receive path, a PA predriver in the transmit path, or as an LO buffer.

Features

• Externally adjustable bias control, set with a single resistor, to meet minimum linearity requirements while minimizing current consumption
• Logic-level gain control that provides a 25dB step reduction in gain, improving IP3 performance for operation during high input signal level conditions
• Supply current reduced from 9mA in high-gain mode to 3mA in low-gain mode
• Logic-controlled shutdown mode, reducing supply current to 0.1μA
• Operates from a +3V to +5.5V supply
• Offered in the miniature 10-pin μMAX package (5mm×3mm) with an exposed paddle
• Performance optimized for use with the MAX2683/MAX2684 3.5GHz SiGe mixers to provide a complete high-performance, front-end solution for 3.5GHz applications

Applications

• Wireless Local Loop
• Wireless Broadband Access
• Digital Microwave Radios
