Description
Summary:	This paper describes a low-voltage fully-integrated CMOS power amplifier for 3.5 GHz mobile WiMAX (IEEE 802.16 standard) subscriber station application based on Chartered’s 0.18 m IC process. Through simulations using a supply voltage of 1.8 V indicate a capability to deliver a maximum output power of 24 dBm to a 50 antenna, with PO1dB of 22.7 dBm corresponding to PI1dB of -1.89 dBm. A power gain of 25.87 dB and a voltage gain of 27 dB can be obtained through a 3-stage cascade configuration, and the power added efficiency (PAE) at PO1dB can achieve almost 24%. In addition, this is the first WiMAX power amplifier that can operate under 1.8 V supply in the literature.
