射频放大器 Autoramping Power Amp for 900MHz Ap

+3.6V, 1W Autoramping Power  Amplifier for 900MHz Applications

General Description

The MAX2235EUP+T 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 +3.6V supply or +28dBm from a +2.7V supply.
