1. 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 50 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
and provides excellent linearity and noise performance, high gain, and good
power-added efficiency.
