MAX2235 - +3.6V / 1W Autoramping Power Amplifier

General Description

The MAX2235 low-voltage, silicon RF power amplifier (PA) is designed for use in the 900MHz frequency band.

It operates directly from a single +2.7V to +5.5V supply, making it suitable for use with 3-cell NiCd or 1-cell Li-Ion batteries.

The device delivers +30dBm (1W) typical output power from a +3.
