Electrostatic sensitive device.
Observe precautions for handling.
Description
Circuitry
The PA’s is designed for low current-consumption 802.11b and 802.11g multi-mode
applications such as Mini-PCI and PCMCIA for portable devices. The low profile
plastic package with internal input matching to 50
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 as well as a linear adjustment of
output power. The PA is realized as a two stage PA with internal interstage-matching
and an open-collector output structure.
Process
The power amplifier is designed in Atmel's Silicon-Germanium (SiGe) process and
provides excellent linearity and noise performance, high gain as well as good power-
added efficiency.
Frequency Range 2.4 GHz to 2.5 GHz
Supply Voltage 2.7 V to 3.6 V
21 dBm Linear Output Power for IEEE 802.11b Mode
3.5% EVM at 15.5 dBm Output Power for IEEE 802.11g Mode
