MAX2335ETI

Overview

The MAX2335ETI+ is an RF front-end receiver integrated circuit designed for CDMA and OFDM applications in the 450 MHz band. It integrates a low-noise amplifier (LNA) and mixer within a single package. The device operates at frequencies between 420 MHz and 470 MHz with a noise figure of 2.2 dB. It requires a supply voltage ranging from 2.9 V to 3.3 V and draws 32 mA of current. The component is housed in a QFN-EP-28 surface-mount package and functions within a temperature range of -40°C to +85°C.
