Maxim MAX2402EAP Datasheet

_______________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.
A shutdown function reduces the current draw to less than 2µA in less than 10µs. The MAX2402 comes in a 20-pin SSOP package to minimize board area.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
