A low-IF WiMAX RF transceiver in 0.18μm CMOS technology

This paper describes a dual band low-IF transceiver front-end for the Mobile WiMAX (802.16e) standard. The transceiver is implemented in TSMC 0.18 mum CMOS technology and covers the frequency ranges from 2.3 - 2.7 GHz. The front end transmitter provides an output gain control of 50 dB with an EVM below 3%, where as the receiver achieves gain of 37 dB and a noise figure of 3.7 dB. The components included in the system are low noise amplifier, Active and passive mixers, voltage controlled oscillator and Class- A power Amplifier.
