CMOS Power Amplifiers for Wireless CommunicationsCMOS Power Amplifiers for Wireless Communications
King-Chun Tsai and Paul R. Gray
Berkeley Wireless Research Center Department of Electrical Engineering and Computer Sciences University of California, Berkeley, CA 94720

Integration in Wireless Industry

Cost, Size, Power Reduction Multi-modal Operation, Ubiquitous Connections Service Integration

Hardware Integration
LC filter Discrete Caps Resonators Frequency Synthesizer

Power Amplifier Discrete Inductors Mixer

DSP Memory

For “system-on-a-chip” scale integration, Si technology possibly the only viable choice
