MAX2602ESA+

The MAX2602ESA+ is a RF power transistor for 900MHz application in 8 pin NSOIC package. This high performance silicon bipolar RF power transistor is optimized for use in portable cellular and wireless equipment that operates from three NiCd/NiMH cells or one Li-Ion cell. It delivers 1W of RF power from 3.6V supply with efficiency of 58% when biased for constant envelope applications (such as FM or FSK). For NADC (IS-54) operation, it delivers 29dBm with -28dBc ACPR from 4.8V supply. Silicon bipolar technology eliminates the need for voltage inverters and sequencing circuitry as required by GaAsFET power amplifiers. Furthermore, a drain switch is not required to turn off MAX2602. This increases operating time in two ways. It allows lower system end of life battery voltage and it eliminates wasted power from drain switch device. The MAX2602 is used in narrow band PCS (NPCS), 915MHz ISM transmitters, microcellular GSM (power class 5), two way paging and CDPD modems.
