General Description
The MAX2601/MAX2602 are RF power transistors optimized for use in portable cellular and wireless equipment that operates from three NiCd/NiMH cells or one Li-Ion cell. These transistors deliver 1W of RF power from a 3.6V supply with efficiency of 58% when biased for constant-envelope applications (e.g., FM or FSK). For NADC (IS-54) operation, they deliver 29dBm with -28dBc ACPR from a 4.8V supply.

Features
♦ Low Voltage: Operates from 1 Li-Ion or 3 NiCd/NiMH Batteries
♦ DC-to-Microwave Operating Range
♦ 1W Output Power at 900MHz
♦ On-Chip Diode for Accurate Biasing (MAX2602)
♦ Low-Cost Silicon Bipolar Technology
♦ Does Not Require Negative Bias or Supply Switch
♦ High Efficiency: 58%
