General Description

The MAX2511 is a complete, highly integrated IF transceiver for applications employing a dual-conversion
architecture. Alternatively, the MAX2511 can be used as a single-conversion transceiver if the RF operating
frequency ranges from 200MHz to 440MHz.

Features

♦ Single +2.7V to +5.5V Supply

♦ Complete Receive Path:

    200MHz to 440MHz (first IF) to 8MHz to 13MHz (second IF)

♦ Limiter with Differential Outputs (adjustable level)

♦ RSSI Function with 90dB Monotonic Dynamic Range

♦ Complete Transmit Path: 8MHz to 13MHz (second IF) to 200MHz to 440MHz (first IF)

♦ On-Chip Oscillator with Voltage Regulator and Buffer

♦ Advanced System Power Management (four modes)

♦ 0.1µA Shutdown Supply Current
