Concurrent Dual Band Transmitter for 2.4/5.2GHz Wireless LAN Applications

The paper reports design of a concurrent dual band transmitter for simultaneous operation at 2.4/5.2GHz. A combination of direct conversion and parallel architectures is utilized to satisfy the requirements of various signal modulation schemes that are employed in wireless local area network. The entire transmitter architecture is implemented using hybrid microwave integrated circuit (HMIC) technology. The system exhibits a maximum data rate of 60-Mbps.
