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.
