MAX2420EAI

The MAX2420EAI is one member of the MAX2420 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. This device includes an on-chip local oscillator (LO), requiring only an external varactor-tuned LC tank for operation. The integrated divide-by-64/65 dual-modulus prescaler can also be set to a direct mode, in which it acts as an LO buffer amplifier.

Features of the MAX2420EAI 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)0.5A Shutdown Mode; (8)Operates from Single +2.7V to +4.8V Supply.

The absolute maximum ratings of the MAX2420EAI can be summarized as:(1)VCC to GND:-0.3V to +5.5V;(2)TXIN Input Power (330 system):-8dBm;(3)Voltage on TXOUT:-0.3V to (VCC + 1.0V);(4)Voltage on TXGAIN, LNAGAIN, TXON, RXON, VCOON, DIV1, MOD:-0.3V to (VCC + 0.3V);(5)RXIN Input Power:10 dBm;(6)TANK, TANK Input Power:2 dBm;(7)Lead Temperature (soldering, 10sec):+300°C;(8)Storage Temperature Range:-65°C to +165°C;(9)Operating Temperature Range:-40°C to +85°C.
