MAX2602ESA

The MAX2602ESA from Analog Devices (formerly Maxim Integrated) is a high-performance silicon bipolar RF power transistor optimized for portable cellular and wireless applications. It operates from low voltages, supporting 1 Li-Ion or 3 NiCd/NiMH batteries, and delivers 1W of RF power at 900MHz with an efficiency of 58% for constant-envelope applications like FM or FSK.

This NPN transistor features a DC-to-microwave operating range and is suitable for use as the final stage in discrete or module power amplifiers. It offers a 15V voltage rating and 1.2A current capability, with a gain of 11.6dB at 1GHz. The MAX2602ESA includes an on-chip diode for accurate biasing, simplifying the bias network and ensuring stable collector current over temperature changes. It does not require negative bias or a supply switch, increasing operating time.

The device is available in a thermally enhanced, 8-pin SOIC package with an exposed pad, suitable for surface mounting. It is screened to an extended temperature range of -40°C to +85°C.

Applications include Narrow-Band PCS (NPCS), 915MHz ISM transmitters, Microcellular GSM, AMPS and Digital Cellular Phones, Two-Way Paging, CDPD Modems, and Land Mobile Radios.
