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
