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

Ω 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 power-

added efficiency.
