This paper presents the design of a Power Amplifier (PA) operates in the 868MHz frequency range for Zigbee Wireless Sensor network (WSN) applications. The PA is designed for 11mW output power. The Cartesian Feedback (CFB) has been applied to the designed PA to improve linearity. The linearized PA designed is designed in UMC 130nm CMOS technology and has ACPR 22dB at 24.3 KHz from the carrier, total output power of 10.4 dBm and transducer power gain 7.6dB. The designed PA consumes 22mW at efficiency of 44.5%for power source 1.2Volt.
