• 35.5 dB gain

• 0 dBm input power

• Gain control range >55 dB

• Integrated power sensor driver

• Low output noise floor of PA <−129 dBm/Hz in GSM RX band

• Wide operating temperature range−20 to +85°C

• LQFP 48 pin package

• Compatible with power ramping controller PCA5075

• Compatible with GSM RF transceiver SA1620.

APPLICATIONS

• 880 to 915 MHz hand-held transceivers for E-GSM applications

• 900 MHz TDMA systems.
