Abstract
Mobile phone handsets include a CMOS front end configured for operating across multiple transmit and receive frequencies. The front end typically includes multiple receivers, each covering a different band allocated for cellular service, and requires large, expensive and power-intensive A/D converters and DSPs. Front-end circuits disclosed herein operate with a broadband software-defined radio (SDR), and include a receive Low Noise Amplifier (LNA), transmit Power Amplifier (PA), and an antenna matching network. The front-end provides broadband operation using relatively low power, and minimizes noise in the received signal.
