MAX2335

450MHz CDMA/OFDM LNA/Mixer

Optimal Front-End Solution for 450MHz Wireless Solutions and Part of Maxim's 3-Chip 450MHz CDMA/OFDM Solution


Please check latest availability status for a specific part variant.

Description

The MAX2335 RF front-end receiver IC is designed for CDMA and OFDM applications in the 450MHz band.

The MAX2335 includes a low-noise amplifier (LNA) with adjustable IIP3 to minimize desensitization due to cross-modulation in the presence of a large interfering signal.

The mixer features differential IF outputs and is designed for high linearity and low noise, which is well suited for CDMA and OFDM applications.

An on-chip frequency divider is included to allow the use of a standard 1GHz VCO. Alternatively, the divider can be bypassed for use with a lower-frequency VCO.

The MAX2335 is available in a 28-pin TQFN package with exposed paddle and is specified for the -40°C to +85°C extended temperature range. The device is also offered in a lead-free package.
