MAX2645 3.4GHz To 3.8GHz SiGe Low-Noise Amplifier/PA Predriver
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
The MAX2645 features a logic-level gain control that provides a 25dB step reduction in gain, which improves IP3 performance for operation during high input signal level conditions. Supply current is reduced from 9mA in high-gain mode to 3mA in low-gain mode. The device also includes a logic-controlled shutdown mode, which reduces supply current to 0.1A. The MAX2645 operates from a +3V to +5.5V supply and is offered in the miniature 10-pin MAX package (5mm x 3mm) with an exposed paddle. Its performance has been optimized for use with the MAX2683 MAX2684 3.5GHz SiGe mixers to provide a complete high-performance, front-end solution for 3.5GHz applications.
