Description This power amplifier (PA) is designed for high-performance 802.11b and 802.11g multi-mode applications such as Mini PCI and PCMCIA for portable devices and access points. The low profile plastic package with internal input matching to 50Ω and on-chip interstage matching minimizes the PCB board-space and allows simplified integration with very few passive components. The on-chip power detector provides a voltage linear to the output power, while the standby/bias control logic provides power-saving and shutdown options. The PA is realized as a three stage PA with internal interstage matching and an open-collector output structure. The power amplifier is designed using Atmel’s Silicon-Germanium (SiGe2) process and provides excellent linearity and noise performance, high gain, and good poweradded efficiency.
