MAX2421EAI

The MAX2421EAI is one member of the MAX2421 family which is designed as the 900MHz image-reject transceiver that can be used in (1)cordless phones ; (2)spread-spectrum communications; (3)wireless telemetry ; (4)two-way paging; (5)wireless networks. And also this device consists of a variable-gain IF amplifier with more than 35dB control range, an image-reject upconverter with 35dB image rejection, and a poweramplifier (PA) predriver that produces up to +2dBm (in some applications serving as the final power stage).

Features of the MAX2421EAI are:(1)Receive/Transmit Mixers with 35dB Image Rejection; (2)Adjustable-Gain LNA; (3)Up to +2dBm Combined Receiver Input IP3; (4)4dB Combined Receiver Noise Figure; (5)>35dB of Transmit Power Control Range; (6)PA Predriver Provides up to +2dBm; (7)Low Current Consump-tion: 23mA Receive, 26mA Transmit and 9.5mA Oscillator; (8)0.5A Shutdown Mode; (9)Operates from Single +2.7V to +4.8V Supply.

The absolute maximum ratings of the MAX2421EAI can be summarized as:(1)Lead Temperature (soldering, 10s): +300°C;(2)Storage Temperature Range: -65°C to +165°C;(3)Junction Temperature: +150°C;(4)Operating Temperature Range: -40°C to +85°C;(5)Continuous Power Dissipation (TA = +70°C) SSOP (derate 9.50mW/°C above +70°C): 762 mW;(6)VCC to GND: -0.3V to +5.5V;(7)Voltage on TXOUT: -0.3V to (VCC + 1.0V).
