General Description

The MAX2402 transmitter integrates a double-balanced mixer, buffered local oscillator (LO) port, variable gain stage, and power amplifier into a single IC. It is intended for use in the 800MHz to 1000MHz band, and is compatible with both direct-sequence and frequencyhopping spread-spectrum designs in the 902MHz to 928MHz ISM band.
